Damn little napoleonic, tinpot, dictator wannabes! Always minding somebody else's business. But it's the way the typical fascist liberal mind works; their life sucks, and they want everyone else's life to suck just as bad. As soon as they get this law passed, they'll be on to their next big urgent busybody quest in life, one that no human being, going back to the dawn of time, ever saw a need for. Conservatives should keep that in mind before jumping on that train with these b***ards.
Hey, I can talk on a cell phone and drive. I can drink a Pepsi and drive. I can talk to passengers in my car and drive. And I can listen to my radio and drive. All safely. And you guys can, too. America's been doing it for almost a century, with not a peep out of anyone -- until the busybodies came along and began massaging the data and otherwise lying with statistics.
Talking on a cell phone is the only activity you listed that requires the person to focus their awareness on two different frames of reference at the same time. That's the difference, and that's why it's dangerous.
