What exactly happened?
Two teenagers in San Mateo had the bright idea of doing a toy gun drive-by, and their bad luck was that their vehicle was a Waymo robotaxi. The autonomous vehicle didn't take kindly to it, let's say. Instead of driving off, it stopped, dialed 911, and waited for the police to arrive.
It's unclear if the kids specifically called a Waymo for the prank or if it was just an unfortunate coincidence. Either way, the robotaxi didn't hesitate. In San Mateo, two teenagers attempted a toy gun prank from a Waymo robotaxi.

How did the robotaxi figure it out?
Waymo's system detected the suspicious activity and initiated emergency protocol. These vehicles are packed with sensors, cameras, and lidar that create a detailed map of their surroundings. They don't miss a detail, let alone a fake gun.

The onboard AI is trained to recognize potentially dangerous situations. Even though the gun was a toy, its shape and the context of the action (a "drive-by") clearly triggered the alarm. Who knew a driverless car could be so diligent?

So, what now?
San Mateo police detained the teenagers and released them to their parents after clarifying the situation. No serious charges, thankfully, but they certainly learned a valuable lesson. Maybe next time they'll stick to water balloons, though who knows if the Waymo wouldn't call the fire department for an impending flood.
This incident reminds us that autonomous vehicles aren't just passive passengers. They are active systems that perceive, analyze, and react to the world. And apparently, they also have a strong aversion to bad taste pranks. Kind of like that aunt who always catches you doing something forbidden.
