The car of the future fixes many of the problems, and it fits right into existing infrastructure. Think autonomous electric single/dual occupant taxis (2+ per lane).
We are still a ways off, but this is where things are headed.
We might not need the parking, but the roads will be useful.
I can't get past the fact that the software, in order to interact with the 3D world, will be expensive and cumbersome to make. Also, people (your income) born before AR tech generally don't want hardware on their face.
This, and Hololens, and similar, will fail for a while, and I'm thinking it will be decades. I'm placing my bet now.
