“According University of Oklahoma Police Department’s BAC Calculator, a 180-lb male registers a .08 after consuming six 12 oz. beers or five gin-and-tonics in a span of two hours.”
This Time article points out that deaths are lower in Sweden, where the legal limit for blood alcohol is .02. In the US, it’s 4 times higher.
In my opinion, the legal limit should be .00. It should be illegal to drink and then drive at all. Some things kill people and we can’t do much about it (natural disaster), or we can’t be too much bothered to invest in the solution (cancer). Some things kill people and we treat it like a necessary evil (war). But some causes of death are preventable, but for the fact that purblind stupidity is endemic to our species.
Duh. How drunk should we let people get, before they go slinging 2 tons of steel around at high speeds?
