The only remaining issue is cost, and that is soon to be sorted out by the imminent invasion of cheap, Chinese lithium-powered EVs.

It's not as gloomy as it sounds! The cost of lithium in automotive use is tumbling as we speak. Last year, a 250 mile range EV costed $550,000. This one costs $80,000. That's a 7-fold reduction in cost in one year!
