Two 15-year-olds in San Mateo, California allegedly spent a Waymo robotaxi ride drinking and firing toy guns out of the window. The car's monitoring systems flagged the behavior, the company remotely disabled the vehicle and called the police, and the ride ended in what officers describe as a high-risk traffic stop. Nobody was arrested — the teens were released to their parents. * The San Mateo police announced all this on Facebook with a line that deserves framing: "Parents do you know where your teens are? @waymo does!" A police department narrating a corporate surveillance event in the voice of a brand ambassador. Exclamation mark included. * NPR's headline played it straighter: "Privacy concerns raised after teens detained by police from a Waymo robotaxi." Look at the grammar, though. Detained by police, from a robotaxi — the car is scenery, a place the teens happened to be, like a bus shelter. But the watching, the flagging and the disabling were all done by a company. The police were the second responders. * NPR's other version — "Waymo called the cops on teen riders" — gets closer, and the reporting under it is genuinely good. It's where you learn that Waymo's cars carry as many as 29 cameras by the company's own description, and that the potential charges are still pending "dependent on what the video from inside the vehicle shows." The car isn't just the scene of the incident. It's the arresting witness. * Two details worth keeping. Police stress the teens "had every right to exit the vehicle before police arrival, but they did not" — somehow the most fifteen-year-old detail in the entire story. And an expert in NPR's own piece names the thing the headline calls "concerns": "It is not clear the extent to which passengers ... are reminded that when they step into the car, that they are being monitored, and most likely they are not told in its entirety how the data will be used." * The fairest counterpoint in the piece comes from a privacy expert, of all people: a cab driver watches you in the rearview mirror too — "You can't have sex in the back of a taxi, right?" True. But the cabbie doesn't archive the footage, and the cabbie's boss didn't field nearly 290,000 government requests for user data in six months — with something handed over more than 80% of the time. * Per Pew, only 5% of Americans have ever ridden a driverless car, and 71% say they'd be uncomfortable in one. The San Mateo two located the accurate reason early, and all it cost them was one deeply awkward call home.
