I am scared to see what the end result will be in US cities, however, because public transit for almost all of the US means poorly run busing routes that nobody wants to take.
Having lived in San Diego for many years (as well as Denver and MPLS which I think are relevant comparisons) I believe that what will happen is that existing (poorly run, poorly utilized) bus routes will be chosen by developers who will use the "blah blah transit blah blah" designation that was just gifted to them to build high end units for people that will drive their cars.
No actual transit (the kind that runs on rails) will be built, some more car-centric housing units will exist at high end prices (they're not going to build garage-less buildings nor are they going to build low end units).
Oh, and the buses will still be empty.
I want this kind of policy regime to be pursued, but they need to build the transit lines first. And buses don't count.
