Thankfully I don't often have a bunch of other cyclists with me as I rarely ride in and out of town near rush hours. I do filter to the front if it's obviously clear and I know I have time based on the lights, I'll usually move off more quickly than the cars anyway as they'll be edging forwards into the ASL while the light is red, then not paying attention when the light actually changes.
