Having just read this thread yesterday morning, yesterday afternoon I was stopped at a red on Ken High St by the south side of Hyde Park, when a nodder undertook me at high speed. So I caught him up (after the light went green obvs) and used the form of words suggested by HatBeard:
me: "When you ran that red, you undertook me at full speed. Was that the safest way you could have passed me?"
him: "Oh oh I was watching you the whole time while I did it"
me: "Sure but why not just overtake me next time?"
him: "Rightly said. Point taken"
me: nod / grunt in an "on your way, citizen" style
