What do phones, brooms, artificial teeth, and mangoes have in common?

These are all things that Indians have left behind in their cabs. One of India’s largest ride-hailing services Uber, on Thursday, released its annual Lost & Found Index naming Mumbai the most forgetful city in India.

Kolkata and Prayagraj came in second and third on the forgetful list. Other cities on the list were Delhi, Kanpur, and Bengaluru, which was also the most forgetful city for three times in a row till the last year.

Uber found that phones, cameras, and bags were amongst the most forgotten wares, followed by utility items like wallets, keys, clothing, and umbrellas, which all made it to the top ten most-forgotten category. Water bottles, headphones, and glasses were other common things that people left behind in their cabs.

Uber says out of the most bizarre and unique things that Indians forgot, were an acrylic artificial tooth, mangoes and a copy of ‘Becoming’ - a book by Michelle Obama. Other items on the list were exam notes, medical prescriptions, teddy bears, and military shoes, to name a few.

Currently, in its fourth edition, the Uber Lost and Found Index India 2020 found that Fridays and Thursdays were the most common days to report lost items, especially around the afternoon lunch and post-lunch lazy lull.

The index even revealed what lost items peaked on certain days. For example, it found that people are most likely to forget a guitar on Saturdays and Sundays, while business card holders are most likely to be left behind on Mondays and Fridays. On Tuesdays, Wednesdays, and Thursdays, people are most likely to forget their lunch, says Uber.
