We define drunkenness by blood alcohol content without adjusting for tolerance. I'm sure there are alcoholics out there whose tolerance is so high that they're perfectly sober at 0.08.

Then there are people like Michael Schumacher or whatever who I'm sure drive better 'drunk' than 99% of sober people.

I wish the police focussed more on the generally shitty soccer mom sub drivers and taxis that try to kill me every day instead of some guy who had two glasses of wine and crossed some arbitrary threshold which may or may not have made him a dangerous driver.
