It is very interesting to read the views of some out there. I really support the idea that some things can't be legislated out of society. I've said on this very site that I think one of the best quotes ever said by anyone was I believe said by Jefferson- although many argue he never did, " a government which governs least governs best." The truth is though, I can't completely support that idea in every instance. See the thing that get's me sometimes with a lot of people who believe that their is nothing that can be done is, well it is completely defeatist and not progressive at all. It's easy to say, "well laws don't stop people from making poor choices" but the lack of progress such a stance creates makes any social progress impossible. In cases like this when an entirely preventable situation is out there, it should be fixed. So if laws are not the answer( which I can certainly agree as true,) we can't just say as a society, "well then no solution is out there", it's simply not good enough.
I've read that some inventions are out there that require the driver to blow into a breathalyzer type thing in order to start the car. Sure, very annoying and not required 99.9 percent of the time, but as was thrown at me this weekend and much more certainly thrown at my neighbors, that .1 percent of the time is beyond terrible.
