All true but...
It assumes that self driving / autonomous cars are ever going to be good enough. Lots of Lidar is a problem. It's easily jammed. Also loads of places where GPS doesn't work. Is the map reading / dead reckoning ever going to be good enough?
Also do most people actually want one, especially if it's small, electric etc and more like a Fiat 500 than a Tesla. Will there be as many form factors as today, or will we (like Apple, MS, Google*) have "tech" companies and sociopathic Silicon Valley folk foisting their vision of what a car should be (probably not for European roads, larger families or fetching DIY stuff)?
