In France in 1973 there where 18000 deaths by motor vehicle. There are
now 3500 but traffic has doubled. That is a big shift in attitude - and
medical response.

Interestingly, the figures have levelled off over the last 10 years,
where the effect of NCAP should be seen. Making people feel too
comfortable, perhaps?

I seem to recall that there is evidence that people are willing to live
with a certain amount of risk and will adapt their behaviour to the risk
level.

It may also be a mistake to seek easy solutions to minimise KSI figures
if the cost of doing so outweighs the benefits. For instance I'm
unconvinced that the change in behaviour that now requires children to
be driven to school rather than walking on their own was a good move.
