Electric cars: If Sir James Dyson can't do it, what’s ‘paper billionaire’ Elon Musk hoping for? What the author completely ignores: a. Dyson vacuums cost more than competitors because it's a better product. Dyson can't make a better EV so they can't charge premium prices like Tesla can. b. Dyson had success in making household vacuums but finds making ev's challenging. Musk also has some prior/current work experience to draw on, like launching rockets... at the same time.
