We don’t know what happened in the alternate universe where there were no seatbelt laws. Maybe there are people here who died because they stubbornly refused to ever wear a seatbelt because they had taken a public stance against seatbelts and made not wearing a seatbelt into a noble fight against tyranny. Maybe in the other universe they’re still alive because they were able to come around and change their mind without feeling like they lost a fight and were admitting defeat.

But I guess we’ll never know, because if you think something is a good idea what you should do is immediately use the government to coerce everybody into doing it under threat of fines and punishment.
