I was about to reply that this is exactly what happened in L.A. in the 1940s and suggest that you look up the "Great American Streetcar Conspiracy", my favorite example of monopolistic conspiracy. But apparently much has changed since I last did that myself, and now the conspiracy seems to be little more than... fake news.
Unless of course we're in the midst of a "Great American Streetcar Conspiracy"-Conspiracy Conspiracy. ;-)
