If my car is unsafe, to me, is it not my own risk assesment to judge? Should we ban extreme sports too? As an adult, I cherish the responsibility of choice.
If you were primarily only putting your own life in danger, sure.
But with driving the way it is now, I do not think it's a leap to make the claim that distracted driving is a danger to not just yourself but to others on the road. It's exactly the kind of thing that the government should be regulating.
