Zero road awareness and complete nob. You have right of way over oncoming vehicles doesn't mean stop when there is only one car behind you and road ahead clear to let cars through. It also doesn't mean then throw your toys out the pram and refuse to move when the road is clear.
no- you dont pass me at 50 mph with a car coming the other way- you slow down, indicate and go fully into the other lane. learn to drive correctly. Look how the mini does it.
Exhaust needs looking at, sounds like a fart in a lunchbox.
