I don't like when people tailgate me(follow me real close). It's not like I'm driving under the speed limit, so there isn't any reason for them scrubs to be on my ass. I've almost had some people run into me after I pumped my brakes. It's just me letting them know they are following me to close. If they run into me, it's their fault.
Also, you got people driving like 80 miles per hour or above on a 55 mile per hour zone. That's just plain stupid and brainless. You got people swerving in and out of traffic so they can get to the red light about 10 seconds before you.
And people on motorcycles seem to think that they don't have the follow the rules that people in cars do. They pass in no passing zones, driving very recklessley, and acting like weirdos.
And people talking on their cell phones while they're driving. Unless it's like en emergency, I don't see why people have to talk on the cell phone so damn much. There have been tons of accidents lately because of these jackasses. There should be a law put in place for the whole US, not just certain states and areas, to restrict people from talking on their cell phones while driving.
