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.

But for aircraft, batteries are a long way off from being viable (well,
for aircraft bigger than radio controlled ones - all of my RC aircraft
are electric, including helicopters weighing almost 7kg)
