Thats kind of what I was assuming
I can see it now......
" Citizen without the seat belt on! Stop resisting!" BANG BANG BANG BANG!!!
I don't think that is the case. Some old cars didn't have seat belts, or some only had seat belts as part of a package back in the day. It would be a real crime to have to put seat belts in some of the old classic cars. Almost as much of a crime as watering down a good scotch with to many ice cubes.
