Going over the Queensferry Crossing, in traffic in the fast lane going about 65MPH. Vehicles in the fast lane were slowly overtaking traffic in the slow lane, which was going around 60MPH. This idiot flies up behind me at a colossal speed. I thought he was going to crash into the back of me. He slams on his brakes but remains so close I couldn't even see the bonnet of their car in my rear view mirror. He then swerved into the slow lane so small that there can't have been more than a foot between him and the car behind him, then undertook me, and swerved out again in front of me. The gap was so small between my car, and the car in front of me in the other lane that my front parking sensors beeped rapidly. I was astounded that he didn't collide with the corners of all of the other 3 vehicles involved. What a tit. He proceeded with this behaviour until he turned off shortly after. Wife took the picture to report to the police, along with rear and front dashcam footage.
Parked across 2 disabled bays at KFC Newark.
