It is pretty cynical and hindsight is always 20/20, but... is self-driving automotive just trains and metros? There is a fundamental business case flaw in these startups, because regulators worldwide will never approve them go together with human traffic, which is messy, chaotic, smart in its own sense at local level (you need to know the uses of local people, not the general rules... eg. driving a car in Naples is very different from driving a car in Milan). Only dedicated lanes or tunnels then, trains!
