This is a very good analogy. Perhaps the best I have heard. Also SSD was with its own 'range anxiety' in that space was always a lot less in your configured system than the spinning disk equivalent. However, advances in automotive are also driven by legislation. The three cylinder turbo charged engines you get in regular European cars are there because of the legislation and that cheating diesel doesn't sell any more. With this continual ratcheting up of legislation there is an incentive for manufacturers to improve the ICE technology. Particularly when efficiency is across the fleet so those inefficient SUVs have to be offset by lean hatchbacks. This means there is incentive for golden bullets, solutions that promise the earth and allow ICE to linger on for longer. Not many of the legacy auto makers can compete in EV sales. They could make the product but the Tesla is hard to beat. They all fall short except when in the subcompact segment where Tesla don't have a product offering.
