Think about why ICE vehicles have radiators and exhaust pipes.
Ever feel the hood of your car or touch the exhaust pipe?
Wasted energy.
Yes that is true. Finding a way to capture that energy is a more sensible idea. In the winter time that energy heats the passenger cabin and the windshield. Isn’t that wonderful.
Teslas have a liquid cooling system on the battery.
The coolant is flammable and is reported to be the cause of some of the fires.
