Interesting comments by Jennifer regarding the Prius - and a well-written review
to boot. For those interested in following up the car angle, there is an Utne
Reader article in the August 2000 issue - "My mileage can beat your mileage" -
which offers another example of computer-mediated information feedback altering
driving behavior.
There is some kind of interesting game logic at work in this; providing this
kind of real-time feedback about the machine, in some fairly obtrusive way,
somehow provides enough pleasure to alter existing habits and practices.
