I also had a roommate from Michigan who said, "Dude, I would never drive home drunk from the bars up there like I do here in Texas. They have checkpoints and they don't mess around."
As weary as I am of the whole Nazi Germany feel of checkpoints, I personally believe that they would decrease the amount of drunk drivers. Just based on my experiences, not necessarily on "facts". Of course they could also end up being horribly abused, as most government programs tend to be.
