I don't get it. I see teslas on the road almost daily here in the frozen north. I can only imagine there's more in warmer climes and where there's more luxury cars on the road. They have some of the highest customer satisfaction levels for any car. They flat out outperform the competition in many regards. He built a better mousetrap, but instead of a mousetrap it was a multi billion dollar project to launch some of the most complicated consumer hardware people can purchase into an extremely mature competitive environment.
Whether or not Tesla survives or wins in the car sector, other manufacturers have been forced to respond to the market disruption.
Calling him a failure seems like an ad hominem attack, really.
