Youths on bikes breaking all the rules

Always happy to shame people on bikes who give law-abiding cyclists a bad name. I see plenty of red-light jumpers or people riding carelessly, that the footage often isn't worth sharing. These "yooves" went to such lengths that I had to shame them: First of all, you need to look closely to see them coming out of the side road at the beginning of the video, as I'm some way off. The road that they are coming out of is a one-way street that they are going the wrong way up. They then exit onto the two-way road but cycle on the right side of the road and then seem surprised when they get a horn sounded at them. They continue riding up the right-hand side of the road to a set of traffic lights where I'd stopped, one of them on the pavement and the other on the right-hand side of the road still, just as they were changing to green. They then continue to ride with one on each side of the road, into on-coming traffic, which can be seen braking as it approaches them, until I'm out if sight.
