additionally, the sensors are not 'weight based' but likely magnetic sensors; depending on the strength of your local advoacy, you can get your city to sensitize the sensors to detect bikes. when the system is sensitive enough to detect bikes, it's amazing. i roll slowly up on some, across the 3- car sensor "gates" at some intersections and watch the lights turn just for me.
I am not really looking for "break the law" advice, it is easy to just go through or push the button, but the whole idea about being VC, at least for me, is that I am following the "laws" of the road.
If the sensor is magnetic, how is my aluminium bike, with aluminium wheels supposed to trip the sensor. Are the few steel parts on my bike enough to work?
