Especially seen from the US: I think that investor thinks that Uber is the future of transport, period. The replacement for buses, local train, taxi, car rental, car ownership. In that world, cities pour money in Uber instead of their failing bus/metro public services. Car manufacturer and insurer are commodities behind Uber, driving is either automated or as cheap as legally possible, but also commodity behind Uber. Basically Uber would be in control of the totality of money for transporting people semi-locally from A to B, which means the lion share of the margin. That's worth 1 trillion or more, even if Uber does not manage everything.
