1. generally speaking the right way to think about accidents/fatalities/hard breaking events is per miles driven given that risk scales with time spent on road (and miles driven is the best proxy we have at the moment, insurance companies use this stat)
2. If wearing a seat belt prevents a ton of fatalities as advertised and generally proven, it would make sense that of the road fatalities that do happen, many are due to not wearing a seat belt.
10% of people not wearing seat belts is still hundreds of millions of miles driven without seat belts.
