Solid state batteries are seen as the Holy Grail. Still, idiot automakers think as follows: electric cars are costly to develop and make, better focus on high-end EVs. Problem is that those cars aren’t exactly lightweights, plus they will have difficulty to compete with conventionally propelled high-end cars, particularly when gasoline prices are low and the sharply contested tax credits are gone.
When you deal with batteries’ inherent low-energy density, better have them propel a car that is as lightweight as possible. Added bonus: these types of EVs will be affordable to buy without needing tax credits, and most definitely to use. They are easier to make driverless too. Too many benefits to pass up on. The waiting is for a newcomer to the auto industry, as Tesla was 14 years ago.
