I had hoped the 'real time' trip and mileage computers put onto some of the well equiped newer cars would help with driver education... from my informal observations and talking with people who have them in their cars, I can't see any evidence they help.
On the other side of the argument, when gas prices were about $4/gal here, I saw a noticable reduction in average speeds on the freeways, and fewer impatient drivers.
