Regarding the hearing issue. These cars already have an Ac. I was thinking they could run it in reverse as a heat pump to save energy on heating. That's how residential heat pumps work both as heaters and ac.

Id think the insulation on electric cars could also be drastically improved. No one ever put much thought into insulating a car since there's free heat from the engine.

The LEAF has a heat pump and it works till about freezing at which point it switches over to an electric heater. The loss of efficiency due to cold weather really dwarfs the cost of heating/cooling in the vehicle.
