A lane change is not worth a life.
A lane change in Los Angeles nearly cost a man his life. As one man tried to pull into a lane from a median, another driver refused to let him in. As the man tried to pull into the lane a second time, the driver once again blocked his car's path. This caused both drivers to get out of their vehicles, sparking an all-out fist fight in the middle of the road that could easily have turned deadly. If ever you needed proof that road rage is totally not worth your aggravation, let this be it.
Stay calm. Drive safe.
