The car of the future should be no car at all.
Bikes, feet, maglev trains, - stuff like that.
Though, I must admit that once I get some money together (or have time to search for a grant) I am going to do an electric conversion of an old subcompact of some kind and build a solar charging station for it.
I would get an EV1 from GM and just build the charging station - but, oh - well, they seem to have destroyed them all.
