Let's not forget that Musk literally said he wants to bore tunnels because it takes him too long to get to work... and this video is essentially showcasing a rapid transit system for people who own his cars.

Musk also claimed Tesla's solar roof would cost less than a "normal" roof... (PS Musk considers a "normal" roof to be made of slate)

The "affordable" (his words) Model 3 has a standard configuration of about $40k.

I think he's a super interesting guy doing amazing things... but I think he's vastly out of touch with what concepts like "affordable" or "normal" mean to the majority of this country. His "normal" doesn't extend very far outside of silicon valley.

He's more Tony Stark than Iron Man.
