This driver should have his license revoked! I was making a right and I had a yield sign. He was at a red light (making a left from the opposite direction than I had been traveling). As I merged, his light changed and he left the intersection at a high rate of speed to beat me to the merge point (his tires squealing). I was already merging, and of course he had to slow down because he was traveling at a very high rate of speed. 100 yards past the merge point, he passed me on the right in a no-passing zone and then slammed on his brakes coming to a full stop in order to give me the finger multiple times (on the road - halting traffic). As we continued to travel ahead, he slammed on the brakes several more times causing a potentially dangerous situation in a 55 mph zone.
Kid in large white sedan didn't like that I was only 5 over the 35 mph limit near oakmont, PA on Freeport Road. Rode my bumper, sped around me, cut me off nearly hitting me then abruptly lane jumped a few times. 6:59 pm 4/1/2017 Freeport Rd right before Hulton Bridge.
Black GMC Terrain weaving all over double yellow line on very dangerous switchback road almost knocking other drivers over cliff when coming around blind curves. All this while tailgating car in front of him.
Passing with oncoming traffic. Forced oncoming vehicle to make evasive maneuvers to avoid being hit head on.
