It would have to be a "real" car, with comfortable seats, air conditioning, stereo, etc., and big enough to feel safe. And, it would have to give a range enough for a fairly long commute, plus a shopping trip at lunch time, plus a side trip in the evening, and then to a restaurant and back. 200 miles might not be enough some days.

Because there are some days when the range is not enough, any pure electric car would have to be one of two or more vehicles. We need to have a vehicle that is capable of long trips, with rapid refueling at commonly available stops during the day. Pure electrics can't do that, at least not yet. We have to go 300+ miles in one day often enough that renting vehicles for those days really doesn't make sense.

A plug-in hybrid makes a lot more sense for the next decade or so. Give me a reasonable commute range on electric-only, and save the small gas motor for the long trips.

When someone develops portable electricity storage cells that can be recharged in a few minutes, and they start adding electricity-pumps beside the gas-pumps at refueling stations, then pure electric will become feasible as an only car. I expect that to begin happening in about another decade, if the government pushes it.
