I know the timing of most of the lights (except this one huge intersection which has some mind bogglingly fast switches, probably because that huge intersection is also insanely busy) so usually I know I'm legit the last one through. I think if you notice the light changing red as you're part way or just about through the intersection that's a pretty good indicator XD

Oh I just realised I have run red lights before, usually on a turn if I've pulled out but didn't end up having the gap I thought I did so was stuck in the middle of the intersection when the lights changed and had to floor it through because there was no going back DX
