This could help support the "what is it really like to feel .08, or .02 or any variance?" question. Maybe I'd answer yes or no depending on my version of what I "think" drinking and driving feels like.

Well, if during one check stop, eg. 3 out of 1000 people are found to be drunk, they can make the assumption that 0.003% of people drive drunk (per time of check stop).
If they compare that number to all the drunk drivers caught in, say a month, they would find that nowhere near 0.003% of the city's 1 million person population was caught, so they can only assume that at any given time, 3000 people are driving drunk, they could assume that 1:1000 people are not being caught.
Keep in mind that many assumptions were made...
