Even if true that doesn't make what I said false. Furthermore common sense also dictates it makes more sense to catch people who are drunk and show signs of it than people who aren't. I know that sounds like what SPC is saying, but we all know if there wasn't a DUI limit at all we'd have hordes of people driving and insisting that they are perfectly OK to do so even if they were at something like 0.15.
I agree with that part, I just don't think it necessarily makes the policy stupid overall, for the reason I pointed out.
