Less than 1/3 of all traffic accidents leading to fatalities involve "influenced" (intoxicated would be even less) drunk drivers. Yet, I would argue that over 50% of municipal and county police budgets are spent in cracking down on drunk driving.
Why are we not cracking down on eating and driving, applying makeup and driving, reading and driving, drinking coffee and driving, changing CDs and driving, removing billboards and other distractions from the sides of the roads, etc.?
My guess for the reasoning behind this would be that most people don't feel that eating, applying makeup, reading, listening to music, and drinking coffee are sins in their own right. A lot of neo-puritans in America however see drinking alcohol, no matter how little or great, as a sin in it's own right. This thought process would be backed up by the fact that statistics showing "Alcohol Related Deaths" account for only the fact that there was a detectable BAC. Yet, the statistics that show "Deaths in which the driver had a greater that .08 BAC" are materially different.
