Losing your belongings on the go can be irritating – especially if they’re valuable or sentimental.

Uber drivers are accustomed to items being left behind in their rides, some more unique than others.

The rideshare’s eighth annual Lost & Found Index, released on Wednesday, surveyed drivers for the most common and surprising possessions left in cars by their passengers.
