drove Tesla, it is very nice and nifty. I also liked very much NeXT cube. IMO this is going to be a stepping stone to next wave of car designs from other Car Companies.
What bugs me is still unresolved issue of battery disposal dismal performance of the car in cold weather. I think this is a very nice leg up to turning car industry and making it innovate perhaps looking for a better all around technology. I hope that what tesla will do instead of providing a nice "copy" for everyone to parrot.
