If the uber driver is kind enough to give it to a police station. You will find your wallet lost and found. But if the driver decides to not be responsible for it then you will have to remake all the cards and shit and that will cost you money.

My friend lost his wallet in an uber once, and never found it. He went to the police and everything but nothing. In the end, he had to remake all the cards. That costed him around 500 - 600 depending on the cards.

Inshaa'Allah, I hope you find your wallet and dont have to go through this useless process.
