Raedwulf -- since you asked relatively nicely this time, imagine the following situation:

I'm at the pub for my local Irish session. I'm there three hours, during which time I drink two pints of beer. This will put me at or over the legal limit of .08% alcohol in my bloodstream.

Still, it's only two pints. When I get in my car to drive home, I contend that I'm as safe and capable as if I had had two Shirley Temples. You would find no sign or symptom of intoxication.

You may or may not believe that, but I know it's a fact. Someone else might be slurring their words or weave in traffic after two pints, making them a hazard to others. I am not.

The point I was making is that the .08 limit is so low as to be silly. Might as well be 0.00, and maybe it should be.

I do not advocate driving while impaired!

Cheers,
Michael
