A motorcyclist gets angry during a roadrage, and regrets it! 

During a roadrage, a motorcyclist slows down a motorist by pulling in front of him and driving at a slow speed (perhaps to stop him and fight him off). The motorist, who simply wants to continue on his way, suddenly accelerates and manages to overtake the motorcycle. But the motorcyclist, obstinate, does not want to let him go and accelerates to try once again to overtake him... He shouldn't have.
