A School District Tried to Help Train Waymos to Stop for School Buses. It Didn’t Work

One of the purported advantages of self-driving car tech is that each car tin larn from 1 vehicle’s mistakes. Here’s however Waymo puts it connected its website: “The Waymo Driver learns from the corporate experiences gathered crossed our fleet, including erstwhile hardware generations.”

But successful Austin, Waymo’s vehicles struggled for months to larn however to halt for schoolhouse buses arsenic drivers picked up and dropped disconnected children. An authoritative with the Austin Independent School District (AISD) alleged that the vehicles had, successful astatine slightest 19 instances, “illegally and dangerously” passed the district’s schoolhouse buses portion their reddish lights were flashing and their halt arms were extended alternatively than coming to implicit stops, arsenic the instrumentality requires.

In aboriginal December, Waymo adjacent issued a national callback related to the incidents, acknowledging astatine slightest 12 of them to national regulators astatine the National Highway Traffic Safety Administration (NHTSA), which oversees roadworthy safety. According to national filings, engineers with the self-driving conveyance institution had “developed bundle changes to code the behavior” weeks before.

But adjacent aft the recall, the school-bus-passing incidents continued, according to schoolhouse officials and a study from the National Transportation Safety Board (NTSB), an autarkic national information watchdog that’s besides investigating the situation.

Now, email and substance messages betwixt schoolhouse officials and Waymo representatives, obtained by WIRED done a nationalist records request, amusement the lengths that the Austin nationalist schoolhouse territory and Waymo went to effort to lick the problem. AISD adjacent hosted a half-day “data collection” lawsuit successful a schoolhouse parking batch successful mid-December, the documents show, with respective employees pulling unneurotic schoolhouse buses and stop-arm signals from crossed the fleet truthful the self-driving car institution could cod accusation related to vehicles and their flashing lights.

Still, by mid-January, implicit a period later, the schoolhouse territory reported astatine slightest 4 much school-bus-passing incidents had taken spot successful Austin. “The information we collected from the opening of the schoolhouse twelvemonth to the extremity of the semester shows that astir 98 percent of radical that person 1 usurpation bash not person another,” an authoritative with the school’s constabulary section told the section NBC affiliate that month. “That tells america that the idiosyncratic is learning, but it does not look the Waymo automated operator strategy is learning done its bundle updates, its recall, what person you, due to the fact that we are inactive having violations.”

The concern raises questions astir the self-driving technologies' funny unsighted spots and the industry’s quality to compensate for them adjacent aft they’ve been spotted.

Self-driving bundle has agelong struggled with recognizing flashing exigency lights and roadworthy information devices with long, bladed arms, including gates and stop-arms, says Missy Cummings, who researches autonomous vehicles astatine George Mason University and served arsenic a information advisor to the NHTSA during the Biden administration. “If [the company] didn't hole this a fewer years ago, the much they drive, the much it’s going to beryllium a problem,” she says. “That’s precisely what’s happening here.”

Waymo did not respond to WIRED’s requests for comment. A spokesperson for the Austin Independent School District referred WIRED to the NTSB portion the incidents are nether investigation. A spokesperson for the NTSB declined to reply WIRED’s questions portion its probe continues.

Illegal Passing

By midwinter of 2025, AISD officials were frustrated. In 1 of the 19 incidents alleged by a lawyer for the territory successful a missive aboriginal released by national roadworthy information regulators, a Waymo passed a schoolhouse autobus letting disconnected children “only moments aft a pupil crossed successful beforehand of the vehicle, and portion the pupil was inactive successful the road.”

“Alarmingly,” the lawyer wrote, 5 of the alleged incidents had occurred aft Waymo had assured the territory that it had updated its bundle to hole the problem. Federal regulators with the NHTSA had already launched a probe into the behavior. “Austin ISD is evaluating each imaginable ineligible remedies astatine its disposal and intends to instrumentality immoderate enactment is indispensable to support the information of its students, if required,” the lawyer warned.
