More importantly, my car has a built in hands free that I can operate by voice. Why should I not be allowed to use it.
Bad example. It's counter-intuitive, but apparently hands-free doesn't actually reduce the risk of a distracted driving accident.
If we really want to make the roads safer, give me the power to arrest the dipshits that fly around me on the Interstate doing 20 miles above the speed limit and changing lanes like they are at Daytona.
You really shouldn't be in the middle lane if people are passing you on the right. Also, If the average speed is 20 over the posted limit, there are a number of states whose traffic laws I think could be interpreted to mean that you are the one who breaking the law and creating a hazard by not keeping up.
There is a technical solution to texting while driving (and also eating cheeseburgers while driving, which iirc is far more dangerous...). It is called autonomous cars. Then you can text and pig out all you want because the car is in control. Once we have one that is demonstrably safer than human drivers, we just need to find a way to deal with all the irrational ninnies who will want to keep the human in control of the vehicle.
