Threat and insult in road transport

Yesterday something happened to me, I will not forget it so quickly. Was yesterday on a federal road. Next to me a dark C class (T-model) drove. In the course of a sharp right turn this came too far on my track. I then honked, did not want to lose my left freshly painted exterior mirror. I then did not take care of it any more. Unfortunately for the C-Class driver was not done. He drove still after me. At the next traffic light he climbed a We…I locked the doors out of fear, but the roof was open and so he hit my roof with his flat hand, spit on me as I screamed and shouted: Hey old man, when I catch you, I hit You dead! At the next traffic light I wanted to confront him. E barricaded himself in his car, also his door was closed. Instead, he clacked with the tongue, which is a misogynistic gesture of my feeling… I thought about it for a long time, but I think, I who d go to the police. If he’s already pre-loaded, because he’s acting like that more often, I may have a chance… What do you think?
