The other big one is people not turning on their headlights when it is getting dark and in the fog. There is just a certain percentage of people that refuse to understand the benefits of headlights in those situations. They figure that if they can see then the lights are not needed. WRONG!!! OK, rant over. I feel much better now.
I like flicking the headlight violators and see what happens. Usually, they turn their lights right on, because they are only unaware that they are off.
