Uber released its annual Lost & Found Index on Tuesday, detailing the items riders most frequently leave behind in vehicles across Canada [1].

The data provides insight into consumer behavior and the logistical challenges drivers face when managing abandoned property. By identifying patterns in forgotten items, the company aims to inform the public about common losses and the recovery process.

Keerthana Rang, a spokesperson for Uber Canada, said the findings highlight the variety of objects left in cars [1]. While many riders forget standard personal electronics or wallets, the index noted several unusual entries. These included dentures, breast milk, and fish [2].

The report also identifies the specific Canadian city where passengers have the highest rate of forgetfulness [1]. This ranking is based on the volume of reported lost items relative to the number of trips taken in those urban centers.

Uber provides a digital process for riders to report missing items and coordinate their return with drivers. The company uses this index to track trends in lost property and to improve the efficiency of its recovery system [1].

Uber released its annual Lost & Found Index on Tuesday.

The release of this index serves as a branding exercise for Uber to humanize its service while providing operational data on asset recovery. By quantifying 'forgetfulness' by city, the company creates a competitive social metric that draws attention to the scale of its Canadian operations and the reliability of its lost-and-found infrastructure.
