Well I'm not sure bikie - couple of reference points for me:
Once a gal and I were sitting just ahead of the crosswalk. We go through a cycle... then another, then a car rolls up behind us... another cycle. Finally we move forward and I motion the car forward. Very next cycle we're a go.
And usually, if there is a car sitting there, I roll up and the light changes in the proper order... but maybe... hmm anyway the crosswalk option works well even at rush hour due to the brief break in traffic on 12th in front of the Pirate Bar.
