In a private car, do I really need a law to cover that case? On public transport (a place where such mandates generally do not exist), I could see the argument because it’s standardizing behavior amongst strangers.

But in my own car, I have no problem telling people to buckle up or GTFO (or not, by my own choice). If I allow them to ride unbuckled, I’m voluntarily taking the risk one will try to go through the windshield via my noggin.
