Discription of Events: He thought I was tailgating him so he pushed on his brakes three times and I backed off and drove far behind him. Well randomly he stops in the middle of the road and puts his flashers on and I try to go around him thinking he was letting me go around him, well when I try to go around him he blocks me in on the other side of the road with his car. He then starts driving again because cars were coming.. When we start driving again, (still not tailgating him), he stops again and does the same thing. Then he keeps goings and stops at a stop sign and just sits there in his car not driving after he stopped at the stop sign.He starts videoing me honking my horn and yelling because what else would you do if someone just doesnt drive. I couldnt go around him, he was literally keeping me there at the stop sign. Then another car comes up behind me at the stop sign and goes right through the stop sign and literally takes off going fast.
