Of course, everyone has an relative who would have been dead if he had been wearing a seatbelt. It's always the case.
I, on the other hand, have been in 3 accidents where there has been a person killed. On my count, there were a total of 11 people involved in those accidents. 4 dead, 1 hospitalized, 6 walk aways. All 4 of the dead were not wearing seatbelts. All 7 of the survivors were.
So I'll take my personal experiences, weigh them against your aunt's miraculous survival story and come to the conclusion... wearing a seatbelt increases your survival odds by a gigantic proportion.
Awesome.
I’m curious, though. Do you believe that there should be a law requiring the wearing of seatbelts?
