Depending on weight, sex, body fat, and how quickly they drink those 1-2 beers, they will fairly easily go over the 0.08 limit by drinking that much alcohol.
According to Wikipedia "However, it is generally accepted that the consumption from sober of one standard drink of alcohol (e.g. 14 grams (17.74 ml) ethanol content by U.S. standard) will increase the average person's BAC roughly 0.02% to 0.05% and would return to 0% about 1.5 to 3 hours later (at a dissipation rate of around 0.015% per hour)."
So one drink is probably OK, but that second drink, depending on a bunch of different variables, might put you into jail. That's where it gets into the gray area. Is a person who has had that second drink an impaired driver? Sometimes I'll feel a little "light headed" after having two drinks. Sometimes, I won't feel at all different after having two drinks. Three drinks, and I'm impaired, without a doubt.
