EGO tripping motorcycle rider got what he asked for. The car was doing the same pace as the cars ahead of him, thats called following the flow of traffic. Tons of room for the rider to pass and move on with his life.....If your so cool and fast just pass the car, why do you have to play games with a car when your going to loose in the end and hurt yourself, your wallet, and possibly even die.
There are alot of factors but sometimes when someone jams on their brakes like that in front of you, you dont have time or panic and all you can do is panic brake and go straight. Thats why is really stupid to do something like that in front of someone, you dont know the condition of their car or the skill of the driver, so how can you be sure they can or will swerve and not hit you? Your playing a dangerious game with something much larger then you! And he just lost....
