of wise men." And yes, the world is full of idiots, but more to the point. Who among us hasn't made a foolish choice sometime or other? If everybody acted wisely, and sensibly, we wouldn't need laws at all. People act in their own selfish interests most of the time, and do stupid things like get angry and act, or get drunk and act, or simply take advantage of others, of which Bernie Madoff is only an extreme example.
In the matter of cell phones, people didn't see the danger, it wasn't immediately apparent to the average person, therefore you need a law.
I gather that the cell phone law in California has reduced accidents by 20% since its enactment. Sadly I don't have a link to that, but I heard it while channel surfing. Perhaps Google will reveal the correctness or incorrectness of that figure. Even if it's 5% it's a worthwhile law.
