Should I say something in the following case?

When riding on or near MUPS, I've started to notice riders paused as if they are
waiting for someone. So it appears they are in fact waiting for me usually, as any rider will do.

Once I pass they get under way and try to keep pace with me. Without fail, they will make an aggressive pass, out of the saddle and sprinting. This seems juvenile and rude to me.

This is almost stalking behavior, as demonstrated by `Eddie in American Flyers`. But as I thought it over, the handful of guilty riders shared these traits: they had new bikes, but were not fully out-fitted with proper riding clothes, nor did they have bike computers. So they didn't have any metrics to train solo.

So I will give them the benefit of the doubt, since they are new to riding. But would it be proper to advise them to gear up and learn how to self-measure their rides, rather than trying to out ride other roadies?

BTW, I've seen 3 different local riders doing this in 2 areas. One guy has `run me down` at least 5 times. I've spoken to him once, saying, `1980's called and they want their setup back.` He is about 30 years younger than me.
