A car has no insulation, as they produce so much waste heat the
engines can provide enough even in the coldest conditions. Adding
insulation, bonded to the cars sheet metal around the cabin, would
improve matters. The drive motors and batteries produce heat, so this
must be available for use.


And also add to the cost and weight...

I doubt that any heat would be available from motors if they are fitted
into the wheel hubs.

There may be problems supplying enough electrical power for the demisters,
seat heaters (oops, well I have a Saab), and other things (maybe needing a
heater for the screen/headlamp wash and other currently unnecessary/rarely
fitted devices).
