Two teenagers used a Waymo robotaxi to conduct a drive-by shooting with toy guns, leading to police involvement and highlighting safety concerns with autonomous vehicle misuse.
<p>Two California teens have learned that Waymo's robotaxis can and will enforce their rider rules on misbehaving passengers. It probably seemed like a marvelous jape—ride around in the back of a robotaxi getting drunk and doing drive-bys, shooting stuff with gel beads. And perhaps it was, until that robotaxi and Waymo worked out what was going on. Waymo then stopped the car and alerted the San Mateo Police, who showed up and detained the troublemakers, <a href="https://www.facebook.com/CityofSanMateoPolice/posts/pfbid0oZgz37UUtDyNHAKPJMeKVGe16ZAm4xc4DJu8mGFNizL5NBYxSHMYgxFSoZ94h9JZl">according to a post</a> on the department's Facebook page.</p>
<p>"After calling us and stopping the car, we were able to safely remove both subjects and determined they were shooting Orbeez from the car as they sipped on afternoon libations while being chauffeured around town in the driverless vehicle," the police wrote.</p>

# Two teens learn the hard way not to do toy gun drive-bys from a Waymo

But[Waymo’s rules](https://support.google.com/waymo/answer/9197501?hl=en)are quite clear: No drug or alcohol use is allowed inside its robotaxis, “regardless of whether permitted by local law\.”
Then again, the two teens broke a few of Waymo’s other rules, too\. For one thing, unless you’re 18 or older, you’re supposed to be accompanied by an adult\. You’re also not allowed to throw anything from the car—which presumably includes shooting toy guns out the window—and weapons are also not allowed\.
And while the teens might have known their weapon was only a SplatRBall gel bead shooter inexpertly painted black, it obviously looked enough like a real gun when seen via the robotaxi’s internal cameras to set off alarms\. \(Waymo says it may review in\-car video under certain circumstances and that “in more urgent circumstances, Support may access live video during a trip,” so there is no presumption of privacy while riding in one\.\)
Indeed, as the police noted, “While there was some ingenuity to this scheme, toy guns, water guns, and BB guns all pose real dangers, especially to an untrained eye\. The simple handling of them can cause fear in passerby’s or to those who don’t get a good look\. Shooting projectiles at speed can cause real damage\. And lets not forget the underage drinking\. All bad ideas today for these two\.”
However, the department did hand it to the teens for at least avoiding a DUI\.
Waymo issued a recall for 3,871 robotaxis after incidents where vehicles entered freeway construction zones at highway speed; a software fix is under development and freeway operations are suspended until it is deployed.
Waymo is voluntarily recalling about 3,800 robotaxis in the U.S. to fix a software glitch that allowed them to drive into flooded roads, following incidents in Austin and San Antonio.
Tesla disclosed details of 17 robotaxi crashes, including two low-speed incidents where remote human drivers caused collisions. The report highlights safety concerns about the use of teleoperation in autonomous vehicle operations.
A Waymo autonomous vehicle avoided a severe collision with a reckless wrong-way driver in Phoenix by taking evasive action, highlighting the safety capabilities of self-driving technology.
Waymo pauses its robotaxi service in Atlanta after a vehicle drove into a flooded street and got stuck, following a similar pause in San Antonio. The company's software recall last week was insufficient to prevent the incident, highlighting ongoing challenges with autonomous vehicles in adverse weather.
