This is a great idea. I already have a car I like very much and cannot see spending money on a new hybrid. I wouldn't ever recoup my money for one. But I sure wouldn't mind getting better than 14 MPG in town. Yeah, that's all I get around town. After all, I only drive to golf courses (all within 5 miles or so) and the occasional (weekly) restaurant (less than 10 miles). The car doesn't even get warmed up properly. I could easily switch to an all electric car but I cannot see paying what they cost. And they would be less comfortable to ride in and not even as much fun to drive.
I'd get a motorcycle which would be cheap on gas and fun to drive but it's hard to carry a set of golf clubs on one... though I have done it.
