I might be saying "en masse" 18 months prematurely. But at the speed utilities move, that's a blink of an eye.
I'm often reminded of Steve Balmer in 2007 laughing at the iPhone: "it's $500 and it doesn't even have a keyboard!?"
Less than 10 years later smartphones are ubiquitous. Not popular--ubiquitous.
That's where EVs are right now: "they cost more and they can't even go 250 miles!?"
EVs will be cheaper than gas cars by 2022, and a few years after that nobody will buy another gas car.
