I'm sorry but I believe there is only one answer. Not to ban cell phones, but the second you activate one, answer an incoming call, or send and outgoing call your car engine dies, or tranny locks into neutral and your forced to pull over.
Should be mandatory, on the federal level, for all states.
that in theory is an excellent idea.
in reality, it would be horrible, and would eventually cause many many accidents.
when your engine cuts, you lose power steering.
you get 1, possibly 2 pumps on the brakes, then your power assist is gone.
so imagine your 20 year old daughter.......small frame, and only weighs 110#. think she'll handle that car at 60mph, in the left lane on the interstate with no power steering or brakes?
it's been allowed to perpetuate itself into our lifestyles. there is unfortunately no stopping it now.
all the rest of us can do is to be more alert.
besides, if they're going to do this for phones, then they'd need to outlaw drinking while you're driving(water, soda, coffee, etc...i know what you thought when you read that!

), eating, and we'd have to turn off the radios, as they're pretty distracting too.
