It would harm my psyche if I thought everyone on the road has been drinking. I actively avoid it during times when it is in fact more likely (New Years eve etc). People who think they know their limits kill people all the time.

So do people who are tired, or old, or stressed, or any other number of reasons. People kill people all the time, singling out one group and basically charging them with pre-crimes is not just. The world is a dangerous place, jailing people so your "psyche" feels good is not just. The world is dangerous, how about you accept that and act accordingly rather than supporting jailing those who haven't hurt anyone.
Perhaps, but drinking and driving is quite a bit more preventable than being stressed. Certainly people get distracted and accidents happen, but purposely driving impaired is in fact something different.
That being said, generally speaking, a drunk driver who happens to not do anything wrong on the road is extremely unlikely to have any legal issues. Mostly they are going to have problems when they start swerving or exhibiting signs of being impaired. A tired driver who is swerving wildly is also likely to get pulled over.

That might be true if it weren't for things like DUI checkpoints, which make it untrue. You can be perfectly fine to drive and still get caught and punished because of what are essentially baseless mass searches.
