Squishmallows, dentures, and an ‘I Heart Hot Dads’ bag: Uber has found thousands of items left in robotaxis
The data is in, and it’s delightfully bizarre: people are leaving their dentures in robotaxis. This year’s Uber Lost & Found Index, a decade-old chronicle of human forgetfulness, has taken a turn for the autonomous. Alongside the standard phones and wallets, passengers in Uber’s fledgling robotaxi fleet—specifically in partnerships with Waymo—have abandoned sets of false teeth, an “I Heart Hot Dads” tote bag, and a hat proclaiming “Emotional Support Human.” The irony is thick enough to chew with

The data is in, and it’s delightfully bizarre: people are leaving their dentures in robotaxis. This year’s Uber Lost & Found Index, a decade-old chronicle of human forgetfulness, has taken a turn for the autonomous. Alongside the standard phones and wallets, passengers in Uber’s fledgling robotaxi fleet—specifically in partnerships with Waymo—have abandoned sets of false teeth, an “I Heart Hot Dads” tote bag, and a hat proclaiming “Emotional Support Human.” The irony is thick enough to chew with those lost dentures.
For Uber, this annual report has always been a PR-friendly piece of anthropological kitsch, a chance to be the whimsical observer of our collective chaos. But this year, it’s serving a dual purpose: to signal that robotaxis are real enough to have their own baggage, literally. The message is clear: the future has arrived, and it’s just as prone to human error as the past.
Let’s be honest, though. This is a clever deflection. The real story isn’t about lost butterflies or ankle monitors; it’s about the messy, unglamorous operational reality of automation. Uber is eager to highlight the “Waymo on Uber” service that finally got its commercial wheels turning in Austin and Atlanta. It’s a monumental technical and logistical achievement. But by focusing on the quirky detritus of these rides, the company subtly glosses over the profound question that haunts every autonomous venture: when you remove the human driver, who becomes responsible for the human mess?
A driver, for all their faults, is a built-in recovery system. They can call you, see your bag sliding under the seat, or have the common sense to chase down a car for a forgotten phone. A robotaxi has none of that. It’s a silent, efficient capsule. The moment the doors close, the chain of custody breaks. Uber’s report frames this as a cute new problem, but it’s actually a foundational business challenge. The “minor business opportunity” of returning items is, in fact, a microcosm of the entire autonomous services ecosystem. It exposes a gap in the loop that technology alone cannot seamlessly close. Someone, somewhere, has to be the human custodian for these driverless pods. Is that a new gig role? An automated retrieval drone? Or a customer service nightmare waiting to happen?
The list of oddities—the live fish, the toboggan—was always a testament to the wild, uncontrollable space of a stranger’s car. Now, with a robot, that wildness feels different. It’s no longer a shared space between two humans; it’s an interface between a human and a machine that has no memory, no discretion, and no empathy. You can’t charm a Waymo into making an exception to return your forgotten “Emotional Support Human” hat. You’re left with a lost property form and a prayer.
This is the real insight hiding in the absurdity. The autonomy Uber is selling isn’t just about removing the steering wheel. It’s about a fundamental shift in responsibility. For ten years, the Lost & Found Index was a funny quirk of a human-staffed network. Now, it’s a stress test for a machine-staffed one. The dentures and the hot dads bag aren’t just punchlines; they’re the canaries in the coal mine for the operational soul of the autonomous age. And right now, that soul looks a lot like a lost and found department run by an algorithm that has no idea what a set of teeth means to its owner.
