Batteries generate a fair amount of heat when they're under load ... otherwise
there wouldn't be all those stories about laptops & phones catching fire. You
can tap the air-flow from battery cooling to heat the passenger compartment.
I think the bigger problem is going to be providing AC to keep the passengers
cool.

Nope, it's just going to take a while for battery technology to catch up to the
needs of long distance driving. That and more depth of charging stations that
can quick charge a vehicle will make electric realistic for longish road trips.
Cabin heating will be a challenge. Right now, cabin heaters take heat from the
engine cooling system, but electric vehicles will have to heat the cabin off the
battery. This will be a range killer with winter driving. I expect AC units will
have some negative effect on range as well.
Personally, I think hydrogen fuel cells are the way to go, but as they have been
tried and discarded, the people who know more than me must know stuff I don't.
Right now, to me as a consumer, electrics are cute toys that show potential to
be useful, but they aren't there yet. I suspect it won't be long though.
