Nine people were standing on a Tallinn bus at six in the evening when a courier robot ran the red light in front of them, and the law’s answer to who pays for their injuries is the bus company. That is not a loophole. It is the design. On Monday, 26 October, a Bolt delivery robot built by Starship Technologies came off Tehnika Street into the pedestrian crossing at Luise, crossed against the signal, and forced a bus driver to brake hard enough to put standing passengers on the floor. Then the robot drove away. Nine people were hurt, and the only party carrying a clean obligation to them is the vehicle that did nothing wrong.
This is the order in which the future arrives: the product ships, the incident happens, and the liability law shows up weeks later with a clipboard. What follows is not a story about one bad sensor.
Andrei Novikov — The Robot Fled, If You Can Put It That Way
The camera on the bus records the collision and the unit being shoved along the roadway. Andrei Novikov, a board member at the municipal transport company Tallinn Transport, reviewed that footage and told ERR’s Russian service that the robot entered the crossing on red — a point the driver and other road users confirmed independently. His summary has the flat accuracy of a man describing something he has already had to explain to a committee: “The robot fled, if you can put it that way.” He judged the driver’s braking correct, and said the consequences would have been far worse had the stop been more sudden.
What the driver did afterwards will never appear in a product brochure. He asked whether anyone needed an ambulance; nobody said yes. He called the control centre, asked what to do, and together they kept the route running — the damage was minimal, it was rush hour, and a bus stopped across that junction would have choked the district. Then he told his employer he could not finish his shift because of his emotional state. Tallinn Transport sent him home and put a replacement behind the wheel. Later, a passenger filed a complaint about their health.
So the ledger balances like this: one robot with a misreading light sensor, one software correction, one driver off the roster for the night. The robot got patched. The man got a ride home.
Pepe Aaviksoo — A Sensor That Has Drifted Is Not Weather
Starship’s head of operations is unusually specific about the mechanism and relaxed about the meaning. It was dark, Pepe Aaviksoo said. An illuminated advertisement sat behind the lights. The pedestrian and vehicle signals lined up in the same sight line. No cars were approaching, so the robot decided to cross. And the unit’s light sensitivity “was not working as it should have and had changed for some reason.”
That clause is the only sentence here that matters technically. A sensor whose response has changed is not a sensor surprised by weather. It is a component that drifted on somebody’s watch between maintenance cycles. His conclusion, delivered on Estonian television, was that “there are many lessons to be learned, but exceptional situations do occur.” Exceptional situations are what engineering is for.
Aaviksoo also disputes the flight. He says telemetry shows the robot pulled to the kerb, contacted the back-office team, waited about ten minutes and moved on only after the bus had gone. His evidence that nobody was hurt is that nobody official came: “we did not detect any rescue vehicles or police at the scene.” A unit that cannot see the passengers on the floor of the bus it just hit is in no position to certify that they were fine.
The admission that should travel further than the crash is about supervision. The robots run autonomously, Aaviksoo said, with an office team able to take over when needed — but the fleet is not continuously watched, because that is “simply not physically possible or economically sustainable, because we have several thousand robots around the world.” Several thousand units sharing pavements with people who cannot see their logs. Scale is the alibi and the problem in one breath.
Lauri Potsepp — The Wrong Party Pays, and That Is the Design
Lauri Potsepp, a board member of the Estonian Motor Insurance Bureau, explained the mechanics to ERR wearily. A bus driver is liable for damage caused to others by the bus regardless of fault. If a passenger falls because the bus brakes hard, that passenger claims against the bus’s motor insurer. Only once the insurer has paid does anyone establish who actually caused the collision — and if the answer is the robot or its operator, the insurer may then pursue the robot’s owner for reimbursement.
Read the sequence again. The injured claim against the wrong party, by statute, because it is the only party holding a policy. The robot’s operator owes nothing on the day and may owe nothing for months, while an insurer assembles a case it has no incentive to hurry. Nine people were hurt by a device that carries no obligation to them at all; their compensation is a line item on the company whose driver saved them.
That is a remarkable position for a wheeled courier to occupy in public space: a traffic participant whose costs are socialised onto whatever it collides with, its own exposure deferred to a second act most injured people never see. The nine on that bus were never its customers. They are its externalities, and the bus company is holding the invoice.
Maria Pashkevich — The Rules Existed, Which Makes It Worse
None of this is a hole in the rulebook. Maria Pashkevich, who heads the road safety department at Estonia’s Transport Administration, told ERR that delivery robots already carry explicit duties: they must be certain a crossing is safe, they must give way, they must not endanger other road users — duties written down, in public, well before this collision. In a crash, the operator must ensure the unit stops and stops being a hazard to everyone else.
Two sentences, and the second is the entire dispute. Nothing was watching the first one being broken at rush hour, in the dark, by a unit whose light sensitivity had quietly changed.
34 Days — The Law That Will Judge the Next Robot Is Not Judging This One
The European Union has already rewritten liability for precisely this category of product. Under Directive (EU) 2024/2853, software and AI systems are treated as products, and the framework applies to units placed on the market or put into service after 9 December 2026. Anything sold earlier stays under the 1985 regime — a law drafted when a defective product meant a badly welded ladder, not a courier that reads a billboard as a green light.
That leaves 34 days. The robot on Luise Street is governed by the old rules, because it was already in service. Every unit the industry puts on a pavement from next year gets the new ones, where the software is the product and the light sensitivity that “changed for some reason” becomes the manufacturer’s statutory problem rather than something to settle later with an insurer.
The next fleet gets the protection. This one got a police report.
11 Million Deliveries — A Track Record Is a Rate, Not a Defence
Starship’s answer is a number, and by industry standards it is a strong one. According to Estonian World, the company operates in seven countries, has completed 11 million autonomous deliveries across 24 million kilometres, and crossed that junction successfully more than 4,000 times before this. Its units have been rerouted away from the intersection while the investigation runs.
Four thousand clean crossings is not a reason to relax. It is the reason the ninth injury was arithmetic. A system that fails once in every few thousand attempts, multiplied across a fleet and a continent and a decade, is not an anomaly — it is a failure rate with a schedule attached. The only question a city should ask is how many people are standing on the bus when the rate comes due.
A device allowed to move through crowds at speed, unsupervised, with no policy of its own, is a policy decision cities have been making by default while waiting for a directive to land.
Nine people fell. One driver went home early. One passenger is still complaining of an injury nobody has priced. The insurer will pay because it must, then go looking for the robot’s owner because it can.
That is the shape of the decade in one intersection: the robot gets a patch, the humans get a claim form, and the law arrives thirty-four days after the people who needed it were already on the floor. The containment systems worked right up until the light changed.
