Your own words, 9 times out of 10 you are driving down the highway at 70 MPH truly believing that you are more than capable of using your cell phone.
That's not quite what I said, but I'll clarify; when I'm doing 70, a rare occurance, 9 times out of 10, there are things I can do on my phone safely. If I'm doing 70, chances are I'm on empty highway. I don't text and drive very often at all, and when I do, I type "Omw" and my phone puts sends On my way I'm driving. Something a person with my driving record can do more safely than your kid can drive to McD's
If you're so worried about your kids and loved ones; don't let them get into a car. Cars are the leading cause of death for teens, and have been long before anyone knew what a cellphone was.
