So you want all people to come to the DMV hammered and drive a closed course to establish how much they can drink and still drive? Do you really find this possible?
.08 is established thru study to be impairment and all 50 states have adopted that level as ground zero.
No- don't be absurd or disingenuous -- you know that states have been strongarmed by the feds to adopt that BAC level. And statistics, which are routinely bent and twisted to support all means of government intrusion, are no reason to arbitrarily incarcerate and ruin the lives of harmless individuals. I have driven for 20 years at a variety of BAC levels from zero to above .08, and my accident rate at all levels is zero - those are some additional statistics for you. And if you think real hard I bet you come up with an idea for a mobile unit to test driving skill and reaction.

This site you cite above states that one is 3-5 times as likely to die in a fatal single driver crash at 0.02.
Why isn't 0.02 an "established by science" limit?
SD
All states adopted .08 as the standard not because of rational decision-making but because the were blackmailed by the federal government and threatened with a loss of funding.
Government by blackmail. Social compact by blackmail.
This is the kind of society you want?
Smoking bans and reduced blood-alcohol levels based not on facts but lies.
That's what you help deliver to those of us who wish we lived in a land of freedom.
