I got a '89 Chevy 1500 pickup...

I can't tell the difference in acceleration if I press the pedal 1/2 way or floor it....

it handles like a drunken cow...

tows nice, but still....

Shutting off your engine at stops a la Prius is not a very good move. If the car's motion is solely resting on the motor, shutting it off would have repercussions on instant unplanned acceleration (ie somebody's decided they would rather not have you around anymore ;>)

There is also a problem with power, an 18mpg 285hp 5.3l Tahoe (just for hypothetical purposes) could probably reach 23mpg max by downsizing or detuning the motor and raising the gear ratios. The problem is, the normal driving Tahoe becomes a dangerously slow slug....

DOD seems a pretty good idea, hoping we don't have a repeat of 1981 on our hands....
