Uber released its 10th [1] annual Lost & Found Index on March 13, 2024, detailing unusual items left in the backseats of vehicles across the U.S. [1].
The report provides a glimpse into passenger behavior and the logistical challenges of ride-sharing. By identifying the most forgetful cities and days, the company aims to improve the rider experience and highlight trends in lost property.
According to the index, drivers discovered a wide variety of unexpected objects during their trips [1]. These discoveries ranged from biological materials, such as breast milk, to live animals, including butterflies [1]. The report serves as a data-driven look at the items that most frequently slip through the cracks of a commute.
Beyond the oddities, the index identifies specific patterns in how and when items are lost. Uber tracked data to determine which U.S. city is the most forgetful and which specific day of the year sees the highest volume of left-behind belongings [1].
The company said the initiative is designed to generate publicity for the brand while providing a service that helps riders recover their property. The Lost & Found Index has become a recurring event for the company, marking a decade of tracking these backseat discoveries [1].

The Lost & Found Index functions as both a marketing tool and a behavioral study. By gamifying the act of losing items and ranking cities, Uber transforms a common customer pain point into a brand engagement opportunity while gathering data on urban mobility patterns.
