Tesla is pretty much the first successful electric car brand in modern times, and there were many others that have failed. While they are here to stay, they aren't out of the woods yet. The Model 3 is pretty basic, and is selling for $35K at minimum. They didn't even put a speedometer on the driver side dashboard, it's just a touch screen in the middle that displays/controls pretty much everything. It's not bad by any means, but it's a far cry from the perfect affordable every man's car.
Meanwhile, Ford, GM, and VW also have very good self driving car systems in the pipeline. Pretty much every major car manufacturer is working on EV technology, and to claim the Chevy Bolt as a failure this year also does not somehow curse General Motors to some sort of permanent failure of an electric car manufacturer.
