I always put my seatbelt (feel naked without it), but I deactivated the ringing in my car, otherwise it's annoying if you have a bag on the passenger seat.
Or maybe a speed limiter. You can’t go over 25mph until the seatbelt is fastened. That would let people move a car in the driveway or something minor, but force them to buckle to get on most roads.
Unfortunately, not wearing a seat belt isn't a risk borne just by the one in the seat. There have been cases of people flying out of their window and battering someone with their body due to not wearing a seat belt. Of course, everything carries a risk of harm to someone else, its a matter of where to draw the line.
We already legally force it in almost every state on public roads because it's not about you, it's about everybody else minding their own business getting killed by your choices.
Doesn't take much FOD on the highway for your unbuckled body to slam into something and now you have a driverless vehicle. Also every else in your car should be bucked too so you're not bumping noggins.
Are you a teenager, because this line thinking crosses into the territory of "I don't need a seatbelt, I'd just use my arms to stop my ass from getting flung out of the window, while having zero clue how physics works.
Do you think of the 6 million police reported auto crashes in 2022 (in the US if you're not from here) that most if not all the people involved would have rather not been in an accident in the first place?
I have a co worker who I won't ride with anymore simply because of that.
