When was an opinion changed in the face of indisputable facts?

What I found most interesting in this thread was: in Maine a BAC of .15 is considered the legal limit? I thought that was a little high, so I found a source to support my argument (wink, wink). Here, let me paste it in for you:

BAC = .12-.15 = Vomiting usually occurs, unless this level is reached slowly or a person has developed a tolerance to alcohol. Drinkers are drowsy.

Drinkers display emotional instability, loss of critical judgment, impairment of perception, memory, and comprehension.

Lack of sensor-motor coordination and impaired balance are typical. Decreased sensory responses and increased reaction times develop. The vision is significantly impaired, including limited ability to see detail, peripheral vision, and slower glare recovery.

7. BAC = .15 = This blood-alcohol level means the equivalent of 1/2 pint of whiskey is circulating in the blood stream.

Here's my source. For me this means about 7.5oz (6 drinks) of 80 proof alcohol within a one hour period.
