Concept cars..is that it?

I cannot even figure out where to enter from, in this thing, leave alone driving one.

or even this thing...

or how about this thing...looks like straight out of some futuristic movie.

and this one is inspired by women's fashion??

it does...doesn't it?

I'm not even sure if they are called cars....hence the non-usage of the noun.
I liked the concept of them running on alternative fuel sources. But, the images sure do make for some neat posters adorned on the walls of a boy's room, not sure about their functionality.
