Ever kicked yourself because you've left something behind in a rideshare? If you live in Atlanta, you're definitely not alone. Uber has released its annual Lost & Found Index, a catalog of the wild things left behind by riders in the last year. The company found that Atlanta is the ninth-most "forgetful" city in the country, meaning that riders here are more likely to leave something than most. While Atlanta is high up on the list, the top spots are taken by New York, Miami, and Chicago.
