Sorry, mandatory seatbelt usage doesn’t make life any safer for car occupants… Really??? I mean, seriously that’s what you think?? You must be joking?
I’ll ask the next guy who goes through the windscreen at the next RTC I go to and ask him if he thinks he should have worn their seatbelt and see what they say.
He’ll say “maybe if I wasn’t going so fast I wouldn’t have had an accident”.
Risk compensation is, as I said, a strange thing. But basically, if you make cars safer (or seem safer) then people drive faster in compensation. John Adams’ book “Risk” is a good read on the subject.
What made a big difference was stricter drink-driving laws. Making seatbelts compulsory had no effect as people just drove faster (so had more accidents but were more likely to survive, hence no difference) – which made things more dangerous for other road users.
An interesting test to do if you don’t believe in risk compensation is to drive along the road, and undo your seatbelt – see what happens to your speed and style of driving.
