The 0.08 limit wasn't arbitrary; it was derived from research that identified at what point alcohol began to significantly affect driving skills.

No, 0.08 IS arbitrary. The old 0.15-0.12 were based on science. I have seen the medical studies with the bend in the impairment curve at that range.

If this is the policy then they should shut down all the bars and not allow restaurants to serve any liquor. Otherwise the the bar or restaurant that served her the glass of wine is also responsible. This is how it works, so if you have one drink and get pulled over you can sue the restaurant for allowing you to leave in an intoxicated condition.
