Wow! That is so cool. I have always enjoyed science fiction, and the first thing I thought about was Heinlein's The Roads Must Roll.
As with any technology that is a reach, there will be plenty of "naysayers" to explain why it can't work. But, clearly, it can. Not a "quick fix." But can be implemented in stages - driveways, parking lots. School playgrounds, sidewalks... developing countries can implement as they build roads vs. retro-fitting... The impact can be fantastic.
Thanks for sharing this, Paul!
