Yup. I had to stop a black cab today and point out that he was driving the wrong way along a one way street.
To be fair, he was apologetic, thanked me and turned around straight away - unlike the cyclist who I met on the same road a couple of hours later.
The cyclist turned against a no left-turn/no entry sign into the road that I was on. As I was coming to the end of the road and intended to turn right, I was well over on the right side. I hit the brakes, lights and horn and came to a stop. He swung across the front of my car, stopping right in front, then passed along my left side, stopping to spit on the car.
Over recent years I have met three cars going the wrong way there and told them, each has been apologetic and thankful - only one continued and that was because he couldn't have turned with the large trailer he was towing.
I have met a fair-few more cyclists than that and all have been rude and then continued on as before.
