For almost any situation, I'd argue it's "greener" to buy a used gas/diesel car and pay a mechanic to maintain it. The monthly budget to save up for repairs should be far lower than a new car payment, and ta least it won't depreciate as much. There was a recent news story about a car designed to jettison its battery pack in case of an emergency, but that wouldn't exactly prevent a parking garage fire. Imagine telling your insurance that your car got hit by an artillerized power pack from an EV parked nearby!
I saw this! What a stupid idea. Now there is a flaming battery flying through the streets...
