If you are seeing news about empty Waymo cars endlessly circling neighborhood streets and cul-de-sacs, you are looking at a very real—and incredibly bizarre—fleet behavior.
This issue is tied to a specific routing phenomenon that occurs when the company expands into a new city.
### The "Staging Ground" Glitch
The most prominent example of this happened in **Atlanta (specifically the Buckhead neighborhood)**. Residents woke up to what looked like a "driverless dystopia": dozens of empty Waymo vehicles creeping down quiet residential dead-end streets, looping around the cul-de-sacs, and rolling right back out, only for another one to arrive minutes later.
* At its peak, neighbors reported up to **50 empty cars an hour** flooding their street between 6:00 AM and 7:00 AM.
* A similar phenomenon famously happened a few years ago in a quiet **San Francisco dead-end street (15th Avenue)**, where a parade of Waymos would drive down the street, perform complicated multi-point turns, and leave—all day long.
### Why is this happening?
The cars aren't technically "lost" or broken; rather, they are falling victim to how their dispatch algorithms handle idle time:
* **Anticipating Demand (Staging):** Waymo’s software continuously analyzes where passenger demand is going to be highest. Instead of paying for massive parking lots, the algorithm tells idle cars to drive to "holding zones" near busy areas so they are ready to instantly pick up riders.
* **The Cul-de-Sac Trap:** When the algorithm selects a general geographic zone to wait in, it tries to steer empty cars away from major, high-traffic arterial roads so they don't block commuters. Unfortunately, the software sometimes identifies quiet, residential cul-de-sacs as the "perfect" low-traffic place to idle. Because the street is a dead end, the cars are forced to immediately turn around or circle, which the algorithm treats as a reset, sending the car right back into the loop.
* **The "Map Bug" Feedback Loop:** If one Waymo successfully navigates a street to turn around, the central system logs that street as a "safe, highly viable route." Other idle cars in the area see this data and think, *"Great, that's a safe place to wait,"* creating a cascading traffic jam of empty robotaxis.
### Human "Fixes" Make It Worse
Frustrated residents have tried taking matters into their own hands, but autonomous vehicles handle street obstacles with extreme caution. In the Atlanta incident, a resident placed a green "children at play" safety sign in the middle of the road to try and deter the cars.
Instead of turning around and leaving the neighborhood, **eight empty Waymos got completely stuck**, paralyzed by the unexpected object in the road, blocking the entire street for residents until remote support could manually override them.
### Waymo's Response
Waymo generally responds to these localized public outcries by manually adjusting their geofencing. Once a specific neighborhood complains and the media picks it up, Waymo’s engineers update their maps to mark those specific residential cul-de-sacs as "no-go zones" for idle staging.
Are you noticing this happening in your own neighborhood, or did you catch one of the viral videos of the r
obotaxi parades?
