The longer tail pipe thing is, whater. Annoying. An E.V. can be charged from any source. Electrons don't discriminate as to what excites them.

Blaiming E.V. power source emisions is like blaming people with second hand smoke cause cancer for their ailment. It's gonna take awhile to regulate the smokers out of our shared space.
