A Question Nobody Thought to Answer
Picture this: a robotaxi rolls through a red light. No human is behind the wheel. A traffic officer watches it happen. Who gets the fine?
It sounds like the setup to a tech-industry joke, but it's one of the most pressing unanswered questions facing cities as autonomous vehicles move from pilot programs into everyday traffic. TechCrunch Mobility flagged the issue this week, and it's a regulatory knot that transportation lawyers, city planners, and AV companies are only beginning to untangle.
The Driver Is the Law's Anchor
Traffic law, as it exists in virtually every jurisdiction on earth, was written with a human driver in mind. The driver is liable. The driver receives the ticket. The driver can contest it in court.
Remove the driver and the whole enforcement chain breaks down. Do you ticket the company that owns the vehicle? The software developer whose algorithm made the wrong call? The passenger sitting in the back seat who had zero control over what happened?
In the United States, where companies like Waymo and Zoox are already operating commercial robotaxi fleets in cities like San Francisco and Phoenix, regulators have mostly been improvising. California's DMV has issued violation notices to autonomous vehicle operators — meaning the companies — but the legal framework is patchwork at best.
Cities Are Feeling the Pressure
The stakes aren't abstract. Robotaxis have already been documented blocking emergency vehicles, getting confused by construction zones, and making traffic manoeuvres that would earn a human driver a stern talking-to from a cop.
When a Waymo vehicle in San Francisco was surrounded by a crowd and set on fire in early 2024, it crystallized how much friction exists between these vehicles and the communities they operate in. Enforcement is part of that friction — if AVs can't be held accountable the way human drivers are, critics argue, they're effectively operating above the law.
Some cities are pushing AV companies to install remote human monitors who can be held responsible for a vehicle's actions. Others want a corporate liability model, where fines go straight to the operator. A few jurisdictions are drafting entirely new traffic codes that treat AVs as a distinct category of road user.
The Technology Is Moving Faster Than the Rulebook
This is the central tension in the autonomous vehicle space right now. The engineering has outpaced governance — not because regulators are lazy, but because the technology arrived faster than anyone anticipated and the edge cases are genuinely hard.
How do you write a law for a situation where the "driver" is a neural network trained on millions of miles of road data? What does "reckless driving" mean when the vehicle has no intentions, only probabilities?
These aren't rhetorical questions. They're the ones that will define how autonomous vehicles integrate into public life over the next decade — and whether the public ever fully trusts them.
The robotaxi era is here. The legal infrastructure to match it is still very much under construction.
