It did just happen to me! My two youngest daughters were riding to school at the beginning of this school year on the school bus, when the driver in the truck following was busy texting. She ran into the back of the bus sending both my daughters to the ER via ambulance, as well as six other students!
I did not call my state rep and ask for a law to be written, I spoke with the seven cops and three ambulance crews and demanded that the driver be given tickets for unsafe operation in a school zone! And she was given three tickets that day (including unsafe operation of a motor vehicle)!
She got off easy with three tickets. I don't know what the penalties for texting while driving would be had that law existed, but I'll bet it would be a lot steeper than that, including loss of license.
The kid who ran into my friend got his license revoked, he won't drive until he's 21. He can text in the car all he wants to now... as long as someone else is driving.
It is not the victims of these preventable accidents who are behind that anti-texting law, it's the police themselves who are lobbying for it. The only statute that they can charge these imbeciles with is "inattentive driving" and they want stiffer penalties associated with texting.
For a law to be changed, usually it involves (1) loss of life and (2) more money for the government.
