I agree with most of what Hobbes said.
The other issue, if your running these high speed 'car-trains' on the open highway, is great uncle Fred, who likes to drive his 1948 Morris Minor, complete with semaphore indicators, on the motorway, sometimes he gets up to 45 mph!!
The 'best' charging system would be induction, so special areas or lanes where power was available, as mentioned your not going to run the whole shebang, its going to be more of a range extender, and probably sold as a premium service as well.
