This happened to me only the bus driver saw me coming down a narrow road and decided to turn into it rather than letting me drive to the end and then him go. He did that inch forward technique making me have to back up
After reversing for him to a small gap i clipped the curb leaving a very nasty and deep gash (those f***ing old style curbs where the stone is all jaggered and uneven) in my three year clean alloys
Tried to complain but they dismissed it. So now, I never let a bus go. I like to think that in the long run I'v won.
Feel your anger!
