Shameless rehashing of a quote I heard on 5Live or R4 a while back.
Hang on while I try and get a source…if I'm wrong, I'll happily retract…y'know me, never afraid to admit I'm wrong 😉
EDIT: Now I remember, it was from the guy who wrote Superfreakonomics…essentially a purely statistical examination, which I see has been roundly rubbished, though as much for the emotion of the statistic as for the stats themselves. Also, it was based on American figures.
Good article with the book excerpt here in the huffington post…Drat, can't do the kinky linky thing. Google Huffington superfreakonomics drink-driving. Should bring it up.
I sort of retract… 😉
