... so they need an engine-powering-a-generator, but other than that, this vehicle rocks! I love the independant wheel drive, and the efficiancy of illiminating the drive train. This illiminates a ton of complexity from the automobile, which should drive the cost down (if not for that stupid battery pack), and TCO as well! I often wondered why Toyota made the Prius "battery assist" to the conventional drive train, effectively making the whole drive train *more* complex, especially with the regenerative breaking.

Anyway, it seems like this is the way forward for all automobiles. Batteries are a crappy storage mechanism, but the advantage to this electric-drive concept is that you should be able to drop in a generator, or fuel cell, or nuclear battery if you wanted, and leave the rest of the car completely intact!
