I'm sure I won't pay you back, and I have to ask him to pay you back. My friend once encountered a similar situation. He directly negotiated with the car rental company and told him that his car did not meet the regulations. If it doesn't matter, tell him that the police want you to take them home for inspection.

If this is still required, call the police directly and say that they rented an illegal tram. If the police come, it will be interesting if they don't care. Looking for the media to expose them, the price of double standards of the police in this era is very serious.
