"How fast can the cars go?"

On the flat, the GM electric car was good for bursts of 75 mph, but I remember watching one in Los Angeles climb the Sepulveda grade during rush hour, during the period that GM gave them out for the extended testing period, in the early '90s.

This little piggy was in the far right lane, going about 20 mph, holding up all the big rigs, and the driver didn't look happy at all. I don't know if he even made it to the top of the grade, since regular traffic was doing 40 mpg and he fell out of sight quickly.

Whoops, 40 mpg should read 40 mph!
