Well, not for cars - there are already all-electric cars with a 200 mile
range. With it being entirely normal for most households to have two or
more cars, it's entirely practical that one be electric in most instances,
since anything that demands cross-country driving can be done in the
other vehicle.

That is 200 miles on the highway with the windows up and no air conditioning.

And in daylight and preferably no hills
