Physical Agents as a Regulatory Category

Why robots, vehicles and drones get rules of their own.

US regulators moved physical AI onto separate tracks in 2026: California opened heavy-duty AV deployment, NHTSA granted Zoox the first robotaxi exemption, and FMCSA exempted driverless trucks. China issued its first mandatory Level 3 and 4 safety standard, effective July 1, 2027; the FAA drone rule is still not final.

Miles before driverless operation: California heavy-duty, per phase 500,000; Aurora logged, 34 trucks 500,000+; California light-duty, per phase 50,000 MILES BEFORE DRIVERLESS OPERATION California heavy-duty, per phase 500,000 Aurora logged, 34 trucks 500,000+ California light-duty, per phase 50,000 MILES

Registry

Seven registry incidents involve physical agents, each under a different regulator

Registry incidents meet a stricter bar than the cases above: public sources name the developer, the failed control and who found it.
