I'd love to see us redeploy parking lots very quickly! But land use transitions in urban areas are going to take more time than throwing up new exurban homes.

That's why we need to get zoning preemptions in place now! 😉 Another wrinkle: if the Waymo strategy of map-every-single-street is first to market, it may well be that urban areas get AVs long before exurban areas. New subdivisions might have to wait years for mapping, just like with Street View.
