This Dyson car idea always did sound weird. I like his reasons for trying. But its very hard to make a decent AND affordable electric car. I have no doubt Dyson could have made a decent one, but to make it affordable they would have needed huge economies of scale, or huge risk-taking balls a la Tesla. And as the article said, there was no point betting their stable existing business on a new moon shot.
Maybe 15 or 20 years ago, before Tesla had kicked the electric car segment up the arse, and the options around were all still pretty crappy, then an expensive Dyson electric car might have made sense. But in todays market it would have to compete with the Tesla Model 3, the Hyundai Kona EV and the Kia Niro EV and there's no way Dyson would have been able to make anything with similar specs at a similar price.
