Maybe we should get rid of speed limits and drunk driving laws too Mr. Michaud. They too ( in your world view) must surely violate personal liberties and are subject to selective enforcement. It is blantantly obvious that cell phone use decreases attention on the roadway. Whether its the woman who came out of a driveway and cut me off yesterday or the flow of traffice on the highway that comes to a sudden slow down when a drive in the left lane decides to make a call and drops his speed 20 mph forgeting about the traffic moving up behind him. The argument that because we cannot erradicate all potential problems 100% of the time is a reason to do nothing is totally ridiculous.

I'm confused by the name of his organization.  Is its purpose to make driving safer for all motorsists, or to allow yahoos to continue a very dangerous practice because their compulsive need to yap when they should be concentrating on driving?  Kind of like drunk drivers organizing to allow driving while bombed, and calling their group Drivers for Responsible Habits.

The MIT study results aren't very different from a hypothetical study that likely would show that people who drink and drive are more likely to take risks, and also be the the worst drivers in a population of drivers. The correlation between drunk driving and bad driving habits while sober might be shakey from a statistically view, but don't lose the point that driving while drunk is dangerous.

I have libertarian streaks, and prefer no rules, but I've learned from observation that libertarian principles greatest weakness is not accounting for stupidity and selfishness.  Your rights to drink, talk on a cell phone, operate an IPad or GPS, etc. while driving end sharply when your behavior imperils the innocent.
