Steve, I spent 15 years designing special machines for the Detroit auto industry. I also have been in the urban transportation business for ten years developing our single wheel motor scooter.
I believe Tesla will be out of business in a few years at best. I won’t go into the details but the electric car does not solve a big enough problem. The problem that needs to be solved for all classes of people is traffic jams. The only thing that will solve that problem is high speed parking. It’s not as glamorous but you give people an extra half hour a day of time back and you’ll have people’s attention.
