Why don't electric cars come with a tiny kerosene cabin heater as standard? A small heater would take up little space or weight, could be easily refueled at home so not need a detour to a petrol station, and be much more cost effective than adding extra batteries just to provide cabin heat. Sure, it's not zero-emission, but the efficiency of a kerosene heater can be pretty good (much better than an internal combustion engine) and it might go a long way to increase the usefulness on cold days.

No one would be silly enough to cart around a tank of highly explosive liquid in their vehicle.

I look forward to hearing my grandkids saying this in disbelief, to which I respond, "No, really, we carted around a massive tank of highly flammable liquid. To make matters worse, we actually steered vehicles ourselves."

I like your thinking. See my other comment for what I think is a good idea for improving the heating situation. https://news.ycombinator.com/item?id=10953036
