I had to read this bit twice:
"Today, with more than 27 million vehicles in Britain, the number
of people
killed on the roads stands at something over 3,000 a year.
Back in 1931 that figure was more than 7,000 - yet there were just
2.3
million vehicles around."
Speed limits, traffic police, drink driving laws, safety cells,
crumple zones, traffic calming, better brakes and lights, ... All
adds up.
Read John Adam's book 'Risk', about "Smeed's Law". See the section,
"Safer Vehicles?", p137. Smeed plotted the number of accidents over
time in various countries. They all followed much the same curve,
although some climbed the curve at a later time than others. Thus
Malaysia in 1980 is just like the USA in 1925. This seems to show
that whatever the improvements were in road design and car design
between 1925 and 1980, they didn't achieve much, if anything.
There were two exceptions: Over the years the Brit's have always
been slightly safer than the curve shows they "should" be, and the
Germans, slightly more dangerous.
