Heterodox

Stephen Dubner, one of the authors of 'Freakanomics' has come up with a bit of original thought in The Times (no more links to Times stories on the blog because the paywall will soon be in place).
Discussing the proposal to lower the drink-drive limit from 80 mg/100ml in blood to 50mg, he makes the point that if you overdo it in the local and choose to walk home then you are between five and eight times more likely to die than if you drive, due to the disproportionately high death rate among intoxicated pedestrians. Of course, the corollary is that you are unlikely to kill anyone else on foot.
