I cant resist it any longer. Everyone's getting confused about diferent
aspects of risk - severity and frequency.
Having just spent a couple of weks in company of a Canadian researcher in
risk and road crashes I think that we need to look at 2 different aspects -
1: frequency of crahses and 2: severity of injury. Seatbelts do nothing for
the first - that's mostly about driver behaviour and a small amount about
car and road engineering. Seatbelts do however have a big effect on the
severity of injury when the crash occurs. So, in places where you have a
choice, it really is your decision on the the severity of injury which you
are willing to risk.
If you want to read more about the impact of engineering on safety read
Gerry Wilde's book on the net: http://psyc.queensu.ca/target/
