Actually the car if you really want to call it that, is a kind of a neat idea. I can see it as useful for short trips around town in crowded cities where parking is at premium and in some European and Asian cities where some of the streets are very narrow. But then again, Ive seen how those people drive. So, yea, no thanks. : ),
I currently have a little Toyota Yaris. I love the gas mileage and how I can easily zip in and out of tight parking spaces and the thing is actually quite peppy on the highway and with the back seats folded down, has a good amount of cargo space. OTOH, I still really miss my SUV.
