I don'y know for sure where you are, but in Denver the sensors are tripped by the em field of the vehicle, not weight as stated in the article. I usually just pulse the starter once or twice and the light changes (my buddy on the BMW doesn't have that option-it sounds like he's grinding coffee if he tries). I have called the traffic engineer's office and (supposedly) they've adjusted the sensitivity to allow for bikes at intersections I've complained about, but I've never heard why they need to be adjusted in the first place.
