I’ll throw you an olive branch and say the registration sticker is completely pointless. The source of truth for whether my car is registered is in a database, not on a sticker. Someone can steal your sticker which results in a false positive for the thief and a false negative (and huge headache) for the victim.

True - but couldn't the same be said for ID then ? Just memorise your license number - cops have been able to look it up in their car computer for years. Saved me at least once.

Typically also they don't even bother with looking at your registration unless the sticker is way out of date

There isn’t a simple mapping between IDs and car registrations. You can borrow a friend’s car without telling the government about it.
