As others have said, as a motorcyclist, my number one concern on the road is a person using their mobile device while driving. I am less worried about road rage (which is still a top concern for me) than distracted drivers.

I see it literally hundreds of times a day. People are driving their cars at over 70mph while texting. They use instagram and facebook at stoplights. They text or call while driving too fast down residential roads. They cause traffic delays because they don't accelerate at a green light for many seconds after the car in front of them has.

I have seen them hit other cars and narrowly miss pedestrians in crosswalks, completely oblivious half the time that they nearly murdered someone.

If I pull up next to them and tell them to put their phone down by pantomime, half the time they flip me off, laugh, or lay on their horn. They do not think they are doing anything wrong and that I am the asshole for telling them to put the phone down.

Distracted drivers are murderers. Distracted drivers are guilty of reckless endangerment. Distracted drivers need to be punished with prejudice. It is statistically more dangerous than driving intoxicated.
