Ride-hailing giant Uber is reportedly aligning with drivers' unions in several cities to slow robotaxi deployments and promote regulations requiring "hybrid networks" that combine autonomous vehicles with human drivers, according to the Financial Times.

The unholy alliance is taking shape in states and cities including New Jersey and Washington, DC, where Uber and organized labor are pushing back against the rapid expansion of autonomous taxi services.

In New Jersey, Uber lobbyists proposed requiring any platform offering robotaxi services to ensure that human drivers provide at least 85% of rides during a three-year pilot program. The ride-hailing company, led by CEO Dara Khosrowshahi, has also joined unions in opposing autonomous vehicle legislation in Washington, claiming that the proposed permitting regime could lock out smaller competitors and platforms such as Uber.

Uber is pitching its effort to slow the rollout of fully autonomous taxis amid mounting competitive pressure from Alphabet-owned Waymo and Tesla's emerging Cybercab. Such regulations, enacted on a city-by-city basis, could eventually create significant obstacles for competing services from Waymo, Tesla, and others that operate without human drivers.

Mandating hybrid networks could preserve Uber's existing dominance and protect its human-driver network while allowing only a limited share of autonomous vehicles. In other words, Uber's newfound concern for labor may have less to do with protecting drivers than with protecting its market share.

The FT noted that Uber remains "behind its arch-rival Waymo" in autonomous driving technology, suggesting that hybrid-network mandates may be designed to protect its market share while the company advances its own robotaxi technology. It would be a great example of weaponizing regulation to slow the competition.
