That's what bugs me about all of his "inventions", is that they aren't really new ideas, or even if they are they're wildly expensive for the benefits. Cities like Vegas look at him and thought "Oh wow finally we'll solve traffic with these new ideas!" when really they just need to invest in actual proven infrastructure like subways and commuter rail.

It's well known that Elon pitched the hyperloop in California because he wanted to kill California's high speed rail, because he'd rather have people buy Teslas then have an inexpensive fast way to travel between cities. He delayed the project for years over his wild claims, and people are still hesitant to it thanks to his selfishness.
