What makes one a good driver is knowing what makes others bad drivers.

A bad driver doesn't have a plan; he merely responds to the stimulus in front of him. A bad driver doesn't know what lane he needs to be in for an upcoming turn, and changes lanes at the last minute.

A bad driver is unaware of the traffic around him. He sits in the left lane of the highway, not noticing the long line behind him. He isn't concerned about what the traffic in front of the car in front of him is doing. A bad driver never knows if the lanes to his left and right are clear.

A bad driver doesn't think about how his actions signal intention, or of how those signals will affect where others drive. He won't use his turn signals because he knows where he's going, what does anyone else care? A bad driver entering a highway thinks that it is the responsibility of those already on the road to make room for him.

A bad driver isn't aware of how lights cycle, so he'll either be speeding to a light that's going to turn red before he gets there, or slowing down traffic to a light that's seconds away from turning green. He'll sit patiently waiting for a light to change, yet when the time gets close THAT'S when he decides to pick up the newspaper and read another paragraph.
