Tesla also would not have survived without government money.
And the idea that Tesla would have "soundly beaten" the other car companies is simply not possible to believe. They make and sell far more cars every year than Tesla has made since its founding. Tesla simply does not make enough cars to satisfy mass market demand. Tesla is not able to do this because its manufacturing processes are not mature.
If every American wanted to buy a Tesla less than a million of them would be able to, and the rest would have to get their cars from the incumbent car companies. It’s hard to see how Tesla could beat the incumbents in such a scenario.
I like Tesla, but come on, be realistic.
