Coming into the city from Newmarket every day this happens to me a lot where I get stuck. It happened to me tonight with the GTA photo tag target too. The key to pressing the button legally is part c. (or was it b) where it states that it's okay to "park/stop" the vehicle if it is visible for 125 m. Show me how your bike is not visible from 125m and I'll agree you're screwed at that intersection. In the case of where I took tonights tag, my bike was clearly visibly from 125m in every direction. 3 cars when right over the loop sensor to turn right and the light did it's crosswalk countdown - then set back to walk again!!! At that point I put the bike in neutral, ensured the flasher was indeed on and working to draw attention to it, dropped the kickstand (it landed RIGHT BESIDE the loop), then dismounted, hit the pedestrian cross button, and walked back to my bike. Lo and behold I had time to mount, pick up the stand, and drop to first all before the count down was complete. I neither impeded traffic, nor broke the no stopping on the street law due to the vehicle being clearly visible. My bike DOES NOT have 4 way flashers so I use the flasher to the closest curb. In this case the left turn island.
At intersections where a car pulls up behind me and stays off the sensor, I wait a few seconds. If they don't get impatient and pull forward a bit, I'll wave them closer.
I had an elderly couple who mis-interpreted this and pulled alongside me and rolled down their window assuming I wanted to say something. I explained to them that my bike wasn't tripping the light and I need them to get in the loop to do so. We all laughed, the light changed and the elderly gentlemen wished me well on my journeys and waited for me to pull off.
The key really lies in too places: communication and common sense. If you blow the light just as a cop comes into view, he's going to tag you and you're going to have a much longer wait than that light was giving you. You'll have to talk your way out of it. If he sees you off your bike but it's in clear view and STILL decides to pull you over, then it'll be a much shorter conversation when you explain to him/her that you waited (for at least 1 or two complete walk/don't walk cycles), before "roadside stopping in lane" your bike in order to trigger the obviously insensitive light. It'll be easier to fight a dismount than a run red. You appear much less in a hurry when you do it.
