Yes, yes, give them your passport, and address, and a phone number, and whatever else they need. What are they gonna do with them? Send debt collectors from Rome to the middle-of-nowhere, Teneese?

When you face a system that was clearly designed by morons, you should remember that they will be just as dumb when it comes to actually enforcing the system.

(Just PSA, if you do live in, Rome, and repeatedly ride without a ticket, after repeated offenses, you'll eventually catch a fine of 1k€+ and if you won't pay that, they'll put you in jail for a few weeks.)

This is a legal advice.
