The Community Collage at Trabant: a Proactive Display in a Cafe

CoCoAtTrabant We recently deployed a proactive display application at the Trabant Coffee & Chai Lounge in the University District of Seattle. The Community Collage (or CoCo) shows a dynamic collage of content drawn from a pool of photos and quotes uploaded to the CoCo web site by customers and staff. When customers visit the café and use their Trabant loyalty cards, their content gets a higher priority to be selected for insertion into the collage. Anyone can visit the web site to view a chronological stream of content that has been shown on the collage, but only registered users can vote or comment on other users' content, post messages on the site's MessageBoard, or send short text messages directly to the CoCo display.

Sample sketchbook page at TrabantThe owners of Trabant, Tatiana Becker and Mike Gregory, along with the baristas and customers at the coffeehouse, have co-curated a creative community space, and we are delighted to have the opportunity to work with all of them. The art on the walls and the music being performed on Mondays (open mic) and weekends reflects some of this creativity, but one of the strongest markers of the creativity that flows through the space is the sketchbooks Trabant has put out on tables in the coffeehouse that various people have contributed to over the years. The sketchbooks reveal a wide variety of depth and breadth of individual personal introspection and community-oriented social, political and artistic commentary - as well as conversations and connections being formed as people riff on each others' words and pictures across space (pages) and time ... a form of reciprocal self-disclosure. One of our goals in deploying CoCo at Trabant is to offer a new channel for expressing this creativity and revelation to all members of the community.

CoCo-Trabant-CommunityCard Given our goal of situated or place-specific community development, we are restricting the population of users to people who visit Trabant. We have printed up business cards (shown to the left) - or perhaps we should call them "community cards" - with a link to our web page, and an invitation code on the back. Customers can pick one up when they visit, and either create an online profile for themselves during their stay (Trabant offers free WiFi - in addition to great coffee) or at a different time or place. The profile enables users to upload photos explicitly, and/or provide a link to their Flickr photo sharing account (if they have one), in which case their Flickr photos are uploaded implicitly. They can also add any number of inspiring quotes to their profile.

TrabantCoCoGiftCard If CoCo users have a Trabant loyalty card (shown to the right) they can enter the code on the back of that card to their profile, so that whenever they use their loyalty card at Trabant, their profile content will be featured more prominently on the collage. The loyalty card is not required: the collage draws content from all users, but it will give priority to those who have - and use - the loyalty cards. And as noted above, anyone can view the content being shared by members of the Trabant community - on the display or on the web site - but only members who have created profiles can vote or comment on the content, or send messages to the MessageBoard or the display itself.

Introducing a new generation of proactive displaysTicket2Talk-UbiComp2003 We call CoCo a proactive display because it senses and responds to the people in a physical space (in this case, a coffeehouse). Although it has an interactive element - people can indirectly interact with the display via the web site - it's primary mode of operation is proactive, showing content relating to people it senses nearby. Earlier examples of proactive displays have involved the use of infrared badges, RFID tags and Bluetooth phones for sensing people, and have been situated in workplace or conference contexts. This is the first time we've deployed a proactive display "in the wild" - a place where you don't need an ID badge to enter, and where the community (and, presumably, the content) is considerably more diverse. We are currently using the Trabant loyalty cards for sensing who is in the coffeehouse, and we currently require an explicit card swipe by the user, but we plan to incorporate other sensing capabilities and explore better integration with existing practices and systems as we progressively refine the design and development of the application.

CoCo is not the first system designed to augment the social space of a cafe. My friend Elizabeth Churchill and her former colleagues at FXPAL created the eyeCanvas, a large touchscreen display that showed content relating to the Canvas Gallery in San Francisco, the place in which it was deployed for a 4-week pilot, and allowed visitors to contribute "finger scribbles" they could draw on a virtual canvas shown on the display. While the Canvas Gallery owners had a profile, of sorts, other users did not have persistent profiles or the ability to upload images (they could, of course, draw images or handwrite quotes to share); I believe this limitation reflected the preferences of the owners rather than the system designers ... and am glad the owners we're working with are so open about enabling other people to share their stuff, on paper (sketchbooks) and now on the big screen.

Another friend, Sean Savage, created PlaceSite, a place-based community web application that enabled people in a cafe to create and share profiles. Unlike CoCo, PlaceSite did not have an associated large display, and the system was more conservative with respect to privacy and did not allow people outside the cafe to access profiles. PlaceSite was piloted at a few coffeehouses in the San Francisco Bay area in 2005 and 2006, but it's interesting - one might even say synchronistic - to note that Sean started formulating the early designs and site selection criteria for the system during his internship with me at Intel Research Seattle in the summer of 2004. He'd even identified Trabant as a promising site, but for a variety of reasons I've alluded to elsewhere, the local Intel lab was not a conducive place to continue pursuing this kind of work, and he decided to postpone deployment until he returned home to the UC Berkeley iSchool, where he was finishing up his master's degree.

Oldenburg-GreatGoodPlace CoCo, eyeCanvas and PlaceSite are all examples of what we might call situated social software - participatory systems designed to reflect the rich digital lives of the people, by the people and for the people in a shared physical space, and [thereby] to promote conversation, connection and community in a quintessential third place. Unlike mobile social software, which enables people to use their mobile phones to maintain connections with their remote friends regardless of time and place, our goal is to use technology to help people establish new connections - or improve existing ones - with the people with whom they are sharing time and space. A quote by Will Rogers captures the essence of this goal:

A stranger is just a friend I haven't met yet.

Many coffeehouses offer wireless Internet (WiFi) access, which enables people to maintain remote connections to their friends in online social networks such as MySpace and Facebook via their WiFi-enabled laptop computers or smartphones. While these online communities offer great value, the cost of maintaining connection with virtual communities is the consequent disconnection with the physical community. Perhaps this is a new variation on Timothy Leary's famous exhortation, "turn on, tune in, drop out": people turn on their laptops, tune in to their online social networks and virtually drop out of contact with the people, places and things around them in physical space.

James Katz offered a great quote in "The New Oases", a recent article in The Economist, describing the impact of WiFi on some of the coffeehouses that offer it: "physically inhabited but psychologically evacuated". Three years ago, I - and others - wrote about the costs and benefits of WiFi use in coffeehouses, triggered by a report that another local coffeehouse - Victrola - had decided to turn off the WiFi on weekends to encourage people to tune in to the people and other things physically present in the place. Trabant offers full-time WiFi, and while we don't want to prevent people from connecting to their virtual communities or compel them to engage with people in the physical coffeehouse - ambience, glanceability and plausible ignoreability are three important design criteria for the collage, to ensure that coffeehouse visitors can [still] enjoy their aloneness together - we want to offer new opportunities to connect with their proximate community.

I've been spending a great deal of time at Trabant lately, and although I spend some of that time virtually tunneling out through the WiFi, CoCo has already helped me learn new things about - and engage in conversations with - the owners, baristas and other customers ... including my creative colleagues on the Strands Labs Seattle team (three of whom - Richie, Shelly and Yogi - are shown in the photo at the top ... and all of whom are, I should note, primarily responsible for the design, development and deployment of CoCo ... I'm just the "front man"). The mission of Strands is to help people discover things they like and didn't know about; CoCo represents a physicalization of this mission, migrating from the online to the offline world(s). We hope that other members of the Trabant community will find that CoCo helps them discover delightful new dimensions of the people, places and things around them!

[Update, June 2009: we've published a paper - "Supporting Community in Third Places with Situated Social Software" - and gave an associated presentation (embedded below) on the system, now called CoCollage, at the 4th International Conference on Communities and Technologies (C&T 2009). Unfortunately, while CoCollage is no longer deployed at Trabant, it can be found in over 20 other venues around Seattle.]

Three Years of Cancer-free Living

Amy had her 3-year checkup this week with Dr. Lonergan at the Cascade Cancer Center. We were delighted to learn that her CT scan showed no sign of the anal cancer she was diagnosed with and treated for in 2005! The overall outcome of the examination was as good as could possibly be expected, and he recommended that she can forego CT scans for future checkups, unless there is any other sign of recurrence. I've never had a CT scan myself, but from what Amy has told me, it is not a pleasant experience (requiring fasting beforehand, and the drinking of a "contrast" solution to help the scanner detect certain internal features more effectively), so this represents a double dose of good news.

When she told me of the news on the phone yesterday, we had just finished discussing a petty issue about which I had been irritated (essentially, a manifestation of my anal retentiveness ... this time, about protecting the floor mats on our new 2008 Honda Civic Hybrid). The sharp contrast between the relative importance of the two phone conversation topics helped me recognize [from Latin recognoscere, to acknowledge or know again] how easily my priorities get out of whack.

Another symptom of how much I've been taking Amy's health for granted is the absence of updates on her previous checkups on this blog (at least since my report on the "all clear" cancer checkup in January 2006, 3 months after the completion of her radiation and chemotherapy treatment). During the period between her initial diagnosis - in May 2005 - and that checkup, I'd been closely engaged in most dimensions of her battle against anal cancer (which I dubbed the "cancer counterinsurgency" in my blog posts ... which, during that period, were numerous and voluminous). She had other annual checkups in 2006 and 2007 - that also showed no signs of recurrence - that I neglected to acknowledge here on this blog ... which probably reflects neglect in other dimensions as well.

One of the many gifts of awareness that Amy has given me over our nearly 20 years of marriage (we celebrate our 20th anniversary on Wednesday) is that talk is cheap ... and by derivation, I suppose this applies to writing as well. So I won't say - or write - much more [now], except to acknowledge my regret for my neglect, and express my intention to celebrate milestones to greater effect (and affect[ion]) ... and my hope that the future will not offer more opportunities to blog about the topic of cancer counterinsurgency.

More Better Design[ers] at Strands Labs Seattle

We're delighted to be joined by two designers at Strands Labs Seattle: Josh Lind and Daniel Norman. Although all of the other members of the team have some knowledge of and experience with design, none of us has been trained as designers, or see that as our primary skill set. With the arrival of Josh and Dan, we have considerably increased our general and specific design capabilities.

DoubleJosh Josh Lind, a local web designer/developer and co-founder of ReadyDone, a talent agency for design, web development and business services, joined Strands Labs Seattle a few weeks ago as a contractor. Josh is a friend of Shelly's, and designed the logo for Swaggle (shown below right), one of the applications created by the company Shelly co-founded, Waggle Labs, and has done some user interface design and development for YourSports, another local startup company that used to be located across the street.

Swaggle-logo Josh brings considerable skills in web design and development, a keen sense of social computing, and [I was pleasantly surprised to discover] a prior awareness and appreciation of some earlier incarnations of proactive displays - large computer displays that can sense people nearby and show content related to those people and their activities in a shared physical space. We're delighted to have him working with us on designing and developing our next generation proactive displays

Danthinking Dan Norman is a graphics designer with experience in both print media and motion graphics (as well as other areas) who recently graduated from Cornish College of the Arts. I discovered Dan via an announcement of the Cornish BFA Art & Design Exposition, showcasing the work of graduating seniors, that I saw on some online event listing site (perhaps After perusing every project on the page, Dan's project, (ad)infinitum, really stood out. It is a dynamic - and dramatic - large screen visualization of pictures from magazine advertisements and tags that people have associated with those pictures. The visualization is very closely related to what we hope to do in our next generation proactive displays.

Dan-thesisShow Delving into Dan's design notebook for his project (a photo of the installation is shown right) - in which he delves deeply into interesting and relevant areas such as semiotics, psychology and linguistics, and their application to advertising - provided further confirmation that our project would benefit a great deal from his involvement. One of the things that resonated most deeply with me was his observation that "the viewer is a co-author", which I believe applies much more broadly than the world of advertising (and I believe Dan believes this, too). Proactive Displays are, in many ways, a vehicle for co-authorship: layering people's personal interests - represented by their online media - in the physical spaces they share with others, actively invites co-authorship among the inhabitants of those spaces ... and our new generation of proactive displays will offer even more ways for people to co-author the content that shows up on a community display. We are delighted that he accepted our offer to join us ... and to do so early enough to help smooth the transition of responsibility for the new dynamic visualization that Sameer has designed and developed for us during his [nearly completed] summer internship with us.

We will be sharing the fruits of all these labors very soon.

Doing Our 2008 Honda Civic Hybrid Duty

WH_HYBRID_34FRONT We have just taken delivery of the first new car we've bought in 8 years (and the first new car we've bought for me in 21 years): a 2008 Honda Civic Hybrid. Ever since watching The End of Suburbia and An Inconvenient Truth, we've been increasingly conscious of the environmental impact of our decisions and actions. We're not ready to move out of our comfortable suburban house - and way of life - yet, but we were eager to make a car buying decision that would better reflect - and enact - our environmental values, and so we decided we were going to buy vehicle with high fuel efficiency ratings (40+ mpg). Since I'm only willing to buy Toyotas or Hondas, this left us with the choice between the Toyota Prius (rated at 48 mpg city / 45 mpg highway) and the Honda Civic Hybrid (rated at 40 mpg city / 45 mpg highway).

Both of these hybrid vehicles are currently in very high demand and very short supply, as the increasing cost of gasoline has provided significant market incentives - as well as environmental ones - for people to purchase and drive fuel efficient automobiles. However, we didn't realize how wide the gap was between demand and supply until we actually started shopping - and that gap is only widening as the price of gas continues to increase (although the decrease in the average price of gas we've seen over the past two weeks - more than 15 cents per gallon, to $3.96 nationwide and $4.23 in Washington - may slow the increase in demand ... temporarily).

We'd been thinking about getting a third car for almost a year - ever since Meg turned 16 - but now that she has a job, and will soon be returning to school, we decided to act. In an unusually swift decision process (for us) - motivated, in part, by the increasing prices and decreasing supplies of the cars in which we were interested - we started car shopping last Sunday afternoon, and placed the order for the car Monday morning.

We made several phone calls, and went to look at - and hoped to drive - cars at Michael's Toyota and Honda Auto Center, both in Bellevue. We went to the Honda dealership first, to test drive a Honda Fit and a Honda Hybrid Civic. Although we eventually decided to restrict our focus to cars that had high fuel efficiency ratings, I've really liked the Fits I've seen on the road. I also liked the Fit I saw at the dealership, and enjoyed driving it too, but Amy was less enthused about its looks, and pointed out that its mileage rating - 27 mpg city / 33 mpg highway - was not nearly as high as the hybrids. Since Amy may eventually "inherit" this car - much as I'd inherited the 1994 Toyota Camry LE Wagon we bought (new) for her 14 years ago - it was important that we both like the car, so we moved on.

We test-drove the one Honda Civic Hybrid they had on the lot. Although the Civic Hybrid reviews at USNews were generally high, their summary of reviews of its performance were not very positive. I found that the performance was fine - Ferrand, one of the salesmen there, took us out on a course that included highway and secondary roads, and going up and down hills, and I thought acceleration during merging on to the highway and going up a hill was fine. Of course, I'm used to driving a 4 cylinder Camry wagon, so my standards may be somewhat lower than performance-oriented drivers. Although we were positively inclined toward the Civic Hybrid, we still wanted to compare it to the Prius, which we expected to like even better (based on reviews we'd read).

We headed over to the Toyota dealership in the hope of test-driving a used Prius - from our earlier phone call, we knew there was a used one, but no new ones, on the lot (and that there are never any new Priuses - Prii? - to test-drive on any lot, as they are all sold well before they arrive, often before they are even manufactured). After a great deal of talking about the Prius - especially in comparison to the Civic (and Toyotas vs. Hondas in general) - the salesman we met there told us there were no new or used Priuses to test-drive. We told him we'd called earlier, and had been told there was a used Prius on the lot; after some phone calls and searching, the salesman was able to find that car - a base-level 2007 Prius - and take us out for a test drive. He didn't propose any course, but as Michael's Toyota is just on the other side of I-90 from Honda Auto Center, we took it on the same course as we did for the Civic. That section of I-90 has pavement that is rather worn - and loud - and we were surprised that we couldn't detect any difference in the level of road noise we heard in the Prius vs. the Civic (in general, Toyotas tend to offer smoother and quieter rides, whereas Hondas tend to offer better handling). We didn't go over any particular rough sections of road, so we couldn't determine whether the ride was any smoother, but the Civic did seem to grip the road better around bends and have a better overall road "feel" than the Prius.

Overall, we just weren't that impressed with the Prius. I've never particularly liked the way they looked from the outside, and on the inside, the base-level 2007 Prius we drove seemed very spartan. I would not be surprised if the higher level packages of the 2008 Prius have interiors that have more to offer, but I don't like to buy a car on faith.

And that, in effect, appears to be what one must do if one wants a Prius - buy it on faith. The Toyota salesman initially told us we'd have to put a $3000 deposit down just to get on a waiting list for some future allocation of Priuses, and that would not be refunded unless they couldn't find a Prius for us in 120 days. If they did find a Prius within that time, we'd have to take it, unless there were some serious defect with it. The cost would be the MSRP plus a mandatory $600 paint & fabric protection plan, which is still less than the average selling price being reported for Priuses. Although we had misgivings about this arrangement, we went into the showroom to further discuss packages, as the criteria one specifies when going on a waiting list affects the length of wait (the more colors and packages one is open to, the more likely an allocated Prius might fit that criteria). We were open to most any color (although I really only like the white and red Priuses), and Packages #2 and #3 seemed to have the most features we wanted - and the fewest we didn't want. We weren't willing to put down the $3000, but were willing to give the salesman our name and number to call us if / when the next allocation was available (which he predicted would be Monday). [Update: Cathy Guisewite expresses this whole situation so much more effectively in a recent comic strip, shown below.]


Having been for a test-drive, and learned more about the uncertainties involved in buying a Prius, we headed back over to the Honda dealership. Ferrand was busy with another customer, so Marco came over to help us. We had another look at the Civic Hybrid, and learned that there were some supply constraints for this car too - the Honda Auto Center had only three more Civic Hybrids allocated for the 2008 model year (the 2009s are expected to start arriving in October) - one white car and two blue ones. They had a blue Civic Hybrid in the showroom (that had already been sold) and happened to have a natural gas powered white Civic (that is [also] not for sale). Amy liked the blue one, but I did not. We both liked the white, although Amy did not like the beige interior fabric that comes with the white Civics. However, Honda subcontracts out to Classic Soft Trim in Renton to replace fabric with leather seating and trim. Amy was very happy with the beige leather sample that Marco showed us, and we decided that if we were going to opt for the Civic (vs. Prius), we'd go for the white exterior and beige leather interior. I wanted to do a bit more research, and it was closing time for the dealership anyway, so we told Marco we'd get back to him the next morning.

The last two times we bought new cars (the 1994 Camry and a 2000 Honda Odyssey EX, which we'll also probably drive for at least 14 years) I spent many weeks - probably months - researching various cars and their various options. In fact, in both cases, I was so thorough in my research that we had friends - who shared our same criteria and priorities with respect to safety, reliability and [other] features - who ended up buying the exact same vehicles we bought from the same dealerships at the same time (and for the same price). This time, we don't have any local friends I know of who are in the market for a new vehicle and share our relatively high prioritization of fuel economy (for that matter, I can't think of any local friends who have bought a hybrid), despite the fact that many of the people in this neighborhood are [also] commuting at least 20 miles each way for work. Since I have no way of directly sharing the wealth of information we've collected, I'm hoping that sharing some of the details of our experience on this blog post might help others benefit from that experience ... another part of my self-assigned 2008 Honda Civic Hybrid duty (and I'll report more about my experience after the first 1000 miles).

Returning to our earlier experiences in car shopping, in both of those cases cases, we were also interested [only] in vehicles in high demand and short supply. For the Camry, which we bought when we lived in Amherst, MA, there were very few LE Wagons on any lots in western New England, and given that I was, in effect, offering to buy two cars - one for us, one for our friends Tony and Carla - I was able to negotiate a price that was $1000 over dealer invoice ($20,633, vs. the manufacturer's suggested list price - MSRP - of $23,316).

Unfortunately, when we bought the Odyssey (while living in Libertyville, IL) - which was in even higher demand and shorter supply, as it was the first model year of their redesigned full-sized minivan, with the "disappearing" fold-down rear seat and dual power sliding side doors - market conditions were more like the current market for the 2008 Prius and Civic Hybrid. We found out about a new Honda dealership in Wisconsin that was getting extra allocations (because it was new); they not only had an Odyssey on the lot, they also had a few more allocations they expected that summer before the end of the model year. We ordered one - and our friends Jack and Donna ordered another - and while we were thrilled to find these vehicles, we ended up paying the full MSRP of $26,415. However, given the market conditions, and reports we'd heard of many people paying $1000 to $2000 above MSRP for their Odysseys, we didn't complain. And, in both cases, we've been quite happy with our purchases (even though Amy has always wished we'd gotten leather seating in the Odyssey, which our friends had installed in their minivan).

In an article in Wednesday's Wall Street Journal, Waiting Game: Patience Pays When Shopping for a Hybrid, Family Money columnist Karen Blumenthal describes her experience in shopping for a Toyota Prius, and notes that Kelley Blue Book pricing for the Prius reveals that the average price paid is currently $1000 to $2000 above the MSRP (as of today, it is listed as $1400 above MSRP), and many people are waiting 3 months or more. The average current selling price for a 2008 Honda Civic Hybrid is $24,434, about $1200 above the MSRP of $23,270 (and about $900 more than the average selling price just one week ago (!)). With the leather seating option ($2000) - an essential feature for Amy - Marco initially offered the car at the asking price of $27,599; this price includes an additional 10% "market adjustment" above MSRP. I countered with the MSRP, plus the leather seating price, ($25,270), and we settled at $26,000. Although this was more than I'd wanted to pay, given current market conditions (which presumably would put the average price, with leather seats, at $26,434), I feel pretty good about the deal. I also found out that as the buyers of a hybrid car, we're eligible for a $525 federal tax rebate, which further ameliorates the pain of paying more than MSRP. And, when we picked up the vehicle yesterday, I discovered that the other two Civic Hybrids have also been sold, so I'm glad we acted when we did.

My new 2008 Honda Civic HybridOverall, we were very happy with the entire experience at Honda Auto Center, and we would highly recommend that dealership in general, and Marco (shown in photo at the right, next to the new car) and Ferrand, in particular. Ferrand was extremely helpful in our test drives, both with his judicious choice of course, with a nice combination of driving conditions within a short distance of the dealership, and pointing out the various features of the Civic Hybrid (and before that, the Fit). When we returned to the dealership Sunday evening, Marco picked up where Ferrand had left off, and helped us better understand some of the features we could better appreciate after having seen and driven a Prius. At no time did we feel any pressure at all, and felt that we were being treated with fairness and honesty throughout the entire process.

Our impressions at the Toyota dealership were rather different. It seemed like the story evolved through a few twists and turns - there are no Priuses available for test drive, or maybe there is one; you need to put down a non-refundable $3000 deposit to get on the waiting list, or maybe you don't - and we came away feeling uncertain about the fairness and honesty we might encounter in future interactions (and potential transactions). To his credit, the salesman did call on Monday, and told me they'd received an allocation, and that he could offer me a white 2008 Prius with Package #2 (though it probably would not arrive for several weeks). By that time, though, we'd already made our decision and I'd already returned to the Honda dealership that morning to put a down payment on our white 2008 Honda Civic Hybrid ... which, much to my delight, arrived at the lot the next day (rather than one or two weeks later, which was the initial estimate). Our decision to buy the Honda Civic Hybrid was primarily based on our relative preference for the car itself (compared with the Prius), but our feelings about the dealers were certainly a part of the overall package.

Our experience at the Toyota dealership reminded me of the expediter that Joel Spolsky wrote about in his recent article on his experience of Starbucks culture and operations, How Hard Could It Be?: Good System, Bad System. Based on something he says he read in the Starbucks Gossip blog (perhaps this comment), Joel says:

For example, I learned from the website that the woman I had seen in the headset taking orders was officially called an expediter -- but the job title is something of a red herring, according to the collective wisdom of the Starbucks staff members chatting on the site.

Expediters are not really there to see to it that a customer's order is filled more quickly, they believe. Rather, expediters exist solely to prevent people in line from giving up and wandering off, maybe to go to the Dunkin' Donuts around the corner. Once a customer places an order, the logic goes, he or she feels an ethical obligation to wait for it to be filled, no matter how long the process takes. Expediters are there to lock in that order as soon as possible.

Given the difference in relative supply between Toyota Priuses and Starbucks coffeehouses, I don't want to make too much of this analogy. I'm sure the Toyota salesman sold the Prius to the next person on his list Monday afternoon, and I'm sure that that person - and most Prius owners (and Michael's Toyota customers) - are very happy with their experiences (which, unfortunately, seems to be less and less the case with Starbucks customers over time).

And speaking of experiences over time, one of the interesting side effects to having test driven the hybrids last weekend was that the real-time feedback offered on their dashboard displays regarding the fuel efficiency (or lack thereof) of my driving helped modify my driving style. I accelerated more slowly, was more opportunistic in both my acceleration (e.g., more willing to lose some speed going up a hill) and my deceleration (coasting up to red lights, stop signs, and traffic backups ... sometimes to the consternation of more aggressive drivers who are behind me), and practiced driving at or below the speed limit (60 mph) on the local highways. In the week since the test drives, my next fillup revealed that these changes in driving style resulted in a fuel economy of 28 mpg on my 1994 Camry, 3 mpg (12%) more efficient than the 25 mpg we've consistently seen over the entire time we've owned the vehicle.

Meg will now become the sole, or primary, driver of the Camry. As a new driver, we're going to be somewhat restrictive in allowing her to drive our first brand new car in 8 years - although _I_ haven't gotten a new car since 1987, we did buy the Camry new in 1994, and a new Honda Odyssey in 2000, but those were both Amy's cars (originally). We may let her drive the Civic early on, just to see whether / how the exposure to the real-time display of fuel efficiency in the Civic might impact the fuel efficiency she might get in the Camry ... and since she'll be paying for her own gas now, that might be an increasingly important "market" factor.
