The most common, unique and downright strange items Uber has returned to riders

Calling all forgetful Uber passengers, you're not the only one who's left their phone or wallet in the back seat -- but there are a few rare riders who forgot a bubble machine, Swarovski crystal binoculars and a Ziploc bag full of quarters.

Uber released its 2020 lost and found data in the U.S. and revealed everything from the most commonly forgotten items -- looking at you cellphones and wallets -- to the most peculiar possessions that continued the ride without its rightful owner.

The ride sharing service also found some interesting trends when it came to brand specific items, which holidays yielded the most forgotten things and the most forgetful cities.

Check out the full list below, including the 50 most unique reported lost items.

Top 10 Most Commonly Forgotten Items

1. Phone
2. Wallet
3. Keys
4. Backpack / bag / purse
5. Headphones
6. Clothing
7. Glasses
8. Vape / e-cig
9. ID / license / passport
10. Water bottle

Where, When and What Items Were Left Behind

New York City, Los Angeles and Chicago didn't even make the top 10 when it comes to the most forgetful cities. Lubbock, Texas, Oxford, Mississippi, College Station, Texas, Fresno, California and Modesto, California, however, were at the top of that list.

According to Uber, "riders are most forgetful on Fridays and Saturdays, and late at night."

"Once again, we saw that some of the most forgetful days of the year were Jan. 1 (New Year’s Day) and Oct. 27 (Halloween weekend), and this year, March 17 (St. Patrick’s Day) made it into the top most forgetful days," Uber said in its release.

Lost & Found Trends:

Luxury left behind
We see our riders leave luxury Louis Vuitton items in Ubers far more often than Prada, YSL and Chanel. Folks hang onto their Fendi and Hermes products.

Key findings
Keys are the third most forgotten items left behind in Ubers. But what brands do we see lost the most? BMW keys top the list, followed by Honda, Jeep and Toyota.

AirPods astray
Headphones also made the top 10 list of most forgotten items, with AirPods showing up again and again. From a lost right pod to the case itself, we saw a more than 21% increase in lost AirPods since last year.

Cash is king
While folks leave all types of money behind - checks, credit cards, bags of coins - we see cash left behind quite often. Folks tend to forget $100 most often, but we’ve seen riders forget $4,000 and even $9,000 in cash!

Color me forgetful
Riders tend to leave behind red and blue items most often, with pink, green and purple items being forgotten frequently, too. Mustard and violet colored items are left behind the least often!

How to Retrieve Lost Items

Uber said the best way to retrieve a lost item is to call the driver directly, but if the item in question is a cellphone, users can login to their account on a computer and follow prompts to contact the driver to coordinate a pickup spot and arrange the return.
