Yes, Tesla as a money-losing R&D company is impressive. You can even go to space privately if you spend enough money....or go to the moon in the 60s...ahem.
I'm sure Musk knows there is first mover advantage but also that most people that invent something end up watching someone else perfect it or market it better.
Big automakers are playing catchup....but they are catching up. Example the Ford Mach E...43k base up to the GT for 59k, quietly already sold around fifty thousand cars this year.
There's a reason auto CEO's are racing to go fully electric. Electric cars require significantly fewer people to design and build. Tesla requires only ten man hours to build a Model Y in Germany, while VW requires 30 to build an ID4. There are fewer parts in electric cars and their assembly is much easier to automate. In addition, the simpler power train means significantly fewer engineers. CEO's love this and can't wait to go fully electric because it means fewer of all types of employees. Unions in Germany and USA are just starting to wake up to this fact.
The proliferation of electric car startups is proof that anyone can start an electric car company now. The barriers for the automotive industry have fallen. Just look at all the new competition from Tesla, Rivian, Lucid, Fisker, Nio, Xpang, Lordstown, and BYD. Rivian's IPO is this week.
The Chinese haven't even entered the US market, choosing first to concentrate on Europe, but they will.
Car dealerships and auto repair are not immune from the electric wave. Cars will be sold online with showrooms in malls like Tesla. Electric cars are can last a million miles if the batteries are replaced and battery technology is improving at a breakneck pace.
