I was intrigued to learn that Musk wanted to build what is essentially a new take on the subway, but after reading this article am totally against the proposal. This is looking far more like an option for rich people to get away from the poors. Short of private helicopters, this is one of the few cities where the public transit option is faster than taking a limo. Musk wants to correct that imbalance by creating a faster option for those who can afford it.
Cities should not support such things. I'm not saying that it shouldn't happen, just that the project shouldn't be given any special treatment, indemnification, or tax breaks. And what do we think will happen to the public option when all the influential people start using the premium service?
Notice also that none of the people in the renderings has any luggage. They aren't even wearing coats. To which magical airport are they headed?
