Two units of alcohol (equivilant to a pint, two small glasses of wine, or two spirit measures) is the legal limit in Britain. I think this is a good benchmark, really, nobody who has been drinking should be driving, however accomodations need to be made for people who finished drinking several hours ago (and has hence gone below the limit but not metabolised all the alcohol) and for the odd drink.
I agree with Peter.
So if a man or woman goes out with his family to the local steak house and gets a beer or two they have no right to drive? Give me a break that is pushing it way to far.
