Nationwide Cell Phone Ban While Driving?

Now, everyone knows that using a cell phone while driving is distracting. Even six states ban the use of cell phones while driving and seven states ban texting while driving. On Sunday, the National Safety Council called for a nationwide ban of using mobile phones while driving (Reuters)

"It's time to take the cellphone away," said Janet Froetscher, president and chief executive officer of the non-profit group. "Studies show that driving while talking on a cellphone is extremely dangerous and puts drivers at a four times greater risk of a crash," Froetscher said in a telephone interview.
You may have heard of the use of a "hands-free" device while using a cell phone and driving. The states above do NOT ban the use of a hands-free device. However, the National Safety Council is recommending all use of cellular phones while driving - including the use of hands-free devices and texting.

Personally, I think this is a little extreme. I admit that I see people all the time kind of paying attention to the road while talking on the phone, or tuning their radio/mp3 player, or shaving, or putting on make up, or eating while driving, or talking to passengers in the car. Banning texting and encouraging use of hands-free devices make sense to me. But banning all use of cell phones while driving. I think that takes it a little too far. What do you think?
