Mark Donahue, former race car driver, did a simulator test with a bunch of normal citizens. They each ran on the simulator and then drank one ounce of alcohol and did it again. When they all were around .07 BAC, Mark had as many accidents and his reaction time was as diminished as all the others.
In short, noboby drives as well drunk or impaired as sober. Drunk driving laws were not meant for inforcement, they were meant to be feared. People consider the penalty if apprehended with the benefit of the crime. Fortunately many are affraid of the law and stay sober.
The absence of other laws and the existence of other types of bad drivers is not a premise to change the existing DWI laws. Naturally the hard core drunk will drink and drive anyway. Most laws, like locks on doors, keep the honest or responsible folks in line.
I would rather ride with a 90 year old guy than a drunk. My odds of getting home are better with the old guy.
On another note: Why are the buttons on the drive through ATM machines also in brail?????
