An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

The motors have never been the problem, it's always been the battery. See train engines, they are a diesel generator with electric motors.

This is where history pisses me off. We should have been headlong into battery research after the oil embargoes. Could have been 40 years faster.

Oil is honestly an amazing product, chemistry wise there is so much we can do with it and energy wise it's a extremely concentrated and easily transported form of energy.

Energy wise one liter of oil is equivalent to 10 person working for a day !

I repeat, using one liter of oil is like having 10 "slaves" working for us for a day.

Its easy to see why oil became the base of our modern civilization, and easy to see why we don't manage to stop using it even though it's destroying us.
