What do you mean ? I trust checked on the internet and he does not have a degree in engineering, so technically he is not an engineer, neither is allowed to practice engineering. He is a businessman and lately he has also become a lobbyist, using his Monday to influence over politics in the United States and other countries.
I believe he would be a bad leader in general and I would not approve the world to have a single leader to rule us all. It would get very distopian rather quick.
The best thing he can do with his money is to mind his own business on electric cars and fight climate change in his way, instead of getting into politics to blatantly.
