Why does disagreeing with you have to mean I sport a tinfoil hat?
I think the tough part is to tease apart which part, when you post an article, you espouse and which not. My immediate assumption upon a posted article is that you completely endorse it. Some of the articles you post are much more extreme than your own views.
But groups like MAAD see only one way to reduce drunk driving - temperance. The less alcohol you can have before getting behind the wheel, the better. So there's nothing especially scientific about the .08 limit; it's mostly politics so far as I can tell.
Well, the exact limit itself certainly is defined mostly by politics since there is a tug-of-war going on.
In my humble opinion, even 0.08 is too high. I mean, my train of thought is that anyone who wants to drive a car on the street should be at the full mental capacity. If they are by nature too stupid too drive, the idea is that they never got the license in the first place.
Now, putting a zero-tolerance in place is problematic because of medications that contain alcohol, or even certain food items. Because of that one must allow for a certain statistical wriggle room around 0.00.
The problem with something like 0.08 is that it inherently says "drink up, just be careful to stay below this arbitrary line", which is a bad message to send. I've seen people routinely do calculations like "if I drink X beers in the first hour, by 2am I will be below 0.08 again, so I should be fine".
