Re Op's post, A similar stich happened to me last month. I spanked that guy's hide but good. He kept catching up at the light, he'd suck off my wheel as long as he could and then fall back frustrated, When the light changed, he'd finally catch up exhausted and woobling ...I kept a steady pace of 19-20... finally after 4.5 miles he turned off.

Gads, get a clue. Either pass or follow. Wanna race? Go to the velo dome.
