The law isn't about impaired and there is no information available about what is impaired. If you are even feeling better after a drink the law states you are impaired. The law is based on a percentage without taking into account the actually quality of driving. Now I am not saying anyone drives better after drinking they do not. But to claim as the law does that everyone becomes a bad driver at .10% and then change it to .08% based on a political organization is pure politics. On the bright side few get pulled at .08% because they are still driving better then a lot of the idiots on the road. A claim could be made that a person who had been drinking a small amount but worried about a DUI may actuall pay more attention while driving so that their impaired driving is superior to idiots who are sober yet talking on the phone or otherwise oblivious to other cars onthe road. I have been unablew to find any research that demonstartes that .o8% causes all drivers abilities to degrade to unacceptable
