All those lane-hoppers and queue-jumpers are idiots, and I always help them to pass me. It is MUCH safer for me to have all the idiot experts in front of me where I am able to keep an eye on them, than behind me and far too close to my Disco tow-ball. The last one that ran into my towball was in a stop-start traffic jam and he was texting ... WHUMP! I pretended I hadn't noticed, and when the traffic moved again I drove away, ripping off most of the plastic front of his car in the process. That all seemed to drop onto the road quite neatly, and there didn't seem much point in discussing the matter with him, he more than likely being such an expert. His problem, not mine. My tow-bracket seems to be pretty strong.
