[Way, way OT if you want to ignore this. Deus just got under my skin here (which he no doubt was trying to do
).]
I'll take your comments seriously, though my inclination is just to treat them as provocative and move on.
Without going into each of the behaviors you mention (some of which are indeed against the law in many places), I'd just say that the relative negative impacts of some forms of behavior (distractions from texting, cell phones, eating or the radio) don't obviate the negative impact of another form of behavior (drinking to the point of legally defined intoxication while driving).
The data on the different behaviors you mention range from compelling to anecdotal. The data on drinking and driving are, however, unequivocal.
And, yep, I have a problem with some of the behaviors you describe. The logical leap to the conclusion "outlaw transportation" is however hyperbolic at best and I really won't argue it.
I'm more or less a Libertarian on societal behavor that doesn't, um, kill people. So, I kind of like laws that protect kids from drunks or otherwise intoxicated folk getting behind the wheel of two-ton vehicles. I also like laws that penalize idiots talking on cell phones or texting for jumping the curb, mowing down pedestrians and ramming into restaurtants or storefronts.
As for folks who are dumb enough to drive while reading or eating in such a way as to impair their ability to manage their vehicle, I would prefer not to bring the law into the picture, but rather I take a Darwinian approach and just hope that they only kill themselves and not others, preferably before they've procreated and further polluted the gene pool.
Guess this is why we should stick to football out here.
