The Fendt tractor driver was walking slowly because he couldn’t be faster than he couldn’t stand the bald acorn in the Mercedes that he had to drive only 40 km / h and started to brake because he wanted to give it back to him without any reason. And it turned out well.
Would you do the same if you drove a tractor and someone would brake intentionally in front of you?
Obviously you should record everything if you want the police to believe you.
