I think it's likely that basic electric vehicles will soon be cheaper than basic gas vehicles. Right now, batteries are the biggest part of the cost (if you want long range), but they're getting cheaper all the time. If you're optimizing for low cost and mass production, you don't need rare-earth permanent magnets in the motor or battery chemistries that require cobalt.

Power grids may be a problem, but it's possible to solve in a decentralized fashion by installing solar panels and/or wind generators near the place where the car is being used. Right now, solar is more available to wealthy people, but there again costs are coming down and in many cases solar is cheaper than buying power from a utility.
