Public transit is a system. Uber will never put the subway out of business, but an Uber bus or other uber services could well nip at peripheral bus lines and make them uneconomic to operate.

This ultimately results in less feeder traffic for the subway, higher subsidy requirements and is overall a bad thing for the system.

Über's valuation is all about the market clout they are building. The fantasies of robot cabs are just a veneer.
