…yes? I thought that’s what license penalties are for.

In some places, yes (Northern Ireland), otherwise we just repeatedly fine.

A better example would be driving drunk, given that you are at an increased risk of injuring others.

You can always lose your license in some places if you are not wearing a seatbelt repeatedly.

Remember that a seatbelt also prevents your body from being a projectile that would be launched against other people in an accident, you're not just a danger to yourself when you don't wear one.

You get a ticket, and too many of those tickets and you lose your license, so yes.

You can if you rack up too many unpaid fines.

In most places with seatbelt laws: yes

Depending on country, yes?
