Uber and Lyft should gain from autonomy, because self-driving developers cannot afford to own the cars, leaving financed local fleets competing for demand the platforms hold. Replacing 10% of US driving takes 2-3 million robotaxis worth $150-300 billion. Robotaxi miles at $0.40-0.60 would undercut car ownership, growing ride-hail roughly 10x. Yet Uber trades near 14x trailing free cash flow and Lyft at single digits. Risks include first-party AV apps, maps or AI agents and safety shocks. x.comÂ
