The subsequent waves of tough DUI laws have been more than tough, they have been vicious. They have been very effective in combating what didn't need to be combated. It now seems that the entire motor vehicles code in most areas is based upon alcohol. With alcohol being the focus of all evil on the modern road, attention has been diverted from many areas where it really is needed. All skill in the American driver has been lost.
Most people just know how to floor it and honk the horn.
Reckless driving is ignored if it has not been induced by an alcoholic beverage or two. The establishment of a standard extrinsic to all evidence of crooked driving is intrinsically flawed. The ability of alcohol to hinder driving ability is as much a factor of how focused the mind is as of how concentrated the alcohol is in the blood. Thus a valley girl may be completely smashed at half the legal limit, while a Tai Chi master may be just fine at twice the legal limit. A standard which does not focus on driving skill fells the innocent and misses the guilty all too often.
