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.

The typical use pattern of a car is driving a few miles twice a day
and then sitting stationary for at least 14 hours in a driveway which
is more than enough hours to charge off a normal power socket. Even
with the windows down and the AC on full blast there's no issue with
range for the typical daily use of a car.

With most households owning two or more cars, the other car can be used
for any cross-country journeys.
