but this could still happen that way too right?
so instead of three states, 1-Go, 2-Yeild, Go if you are to close, 3-Stop
you have 4? 1-Go, 2-Still Go, but speed up because yeild is coming, 3-Yeild, but be careful because the guy behind you sped up because it was solid green, 4-Stop?
I think I like 3 better...maybe your yellow isn't long enough...
