There are several people at my work, young mostly, who don’t own a car and use Uber for their daily commute. I suspect they’ve got this right from a costs perspective. Car ownership is costly and a hassle.
Their great ideas fail when they and their partner have children. Suddenly public transport becomes a real pain. What they may buy into is shared vehicle on demand, but in both cases they won't want to live in city centres that discriminate against cars. In our family my nephew and partner moved from a glorious apartment in Wimbledon became a victorian detached house in Purley, plus a car..
