The boring company has been a scam too. It's a vehicle to kill real public transportation projects. The Vegas tunnel could've been a subway, but instead it's a low capacity vehicle tunnel that's barely a viable alternative to walking.

The way it works is this: they underbid on projects that would reduce car dependency, the government goes for the lower priced solution, Elon builds a tiny tunnel that has a fraction of the capacity of a tunnel that would fit a train. Nobody uses the new tunnel because it's not real public transport and the car dependency status quo is maintained.
