Few States Ban Cell Phone use while Driving

Why is it that so few US states have banned, or are even debating the ban of cell phone use while driving, when most other countries have!
Talk about this country being behind the times!
How many more people must get injured or die in an accident because a driver wasn't paying attention while talking on a cell phone?
I am sick do death of this issue!
Every time I see a car doing something erratic I look to see the driver and sure enough there's a doggone cell phone in their ear!
Let's get it together folks! If you use a cell phone, don't while driving!
