Reply #9: Just on the point of interlock devices (breathalyzers)

I've known two people with them. They are dangerous. Your car gives you 5 minutes to find a "safe" place to pull over and wait for several minutes every hour. Then at random intervals while driving you have to blow and do a complex button/blow routine or you get a huge fine. Also, it will give false positives for all sorts of things including vinegar and mouthwash. It also takes up to several minutes to get your car started. All of that is fine if you're in no danger, but I can think of many situations where your life could be threatened just by your inability to drive away. The two people I knew that had it were young females. I always worried when they were on the highway.
