Judged by the person who thinks putting cars in tunnels is the solution to urban transit? No thanks. Your average third grader is a more qualified engineer than Elon Musk.
Elon Musk is not an engineer. He hasn't built a thing is his entire life. His biggest accomplishment is hitching a ride on the success of Paypal before getting fired for trying to move their infrastructure to Windows (lol).
My niece, on the other hand, just built a pretty cool rocket out of a soda bottle!
If SpaceX is less comically incompetent than Tesla, I'd wager it's because Elon Musk hasn't been paying as much attention to it.
