This clip, from WGBH's NOVA, shows various electric car alternatives including Click and Clack's sadly brief drive in a Tesla Roadster.

For those who are not aware, the Tesla is the world's first production electric sports car, an amazing feat of derring-doo and engineering. Over a year late, Teslas are only now starting to dribble off the assembly line in agonizing slowness, but at least they are coming.

The film seems to have been back in the good old days when Martin Eberhard was in charge, since he is featured and it looks like both Martin and the Brothers were driving prototypes.
