I didn't go home and find any tables to support/undermine his figures.
Sadly that's exactly the kind of thing lonely internet geeks like me enjoy doing 😀
Looking at the 2003 report, they didn't give such a full Contributory Factors breakdown back then, but it does state:
Excessive speed was the most frequently cited contributory factor to fatal accidents, recorded in 28 per cent of such accidents between 1999 and 2002. This compares with 18 per cent of severe accidents and 11 per cent of slight accidents.
So it still accounts for 11% even if you only look at the minors.
Of course these are "reported accidents", most "scratched paint" accidents aren't likely to be reported, so wouldn't be covered by these figures. It may well be that 95% of ALL accidents, including the non-serious unreported ones, occur in those conditions.
But you can't really use the number of scratched-paint accidents where no one was speeding to support your statement that "THUS SPEED DOES NOT KILL".
