Maybe cyclists should just be allowed to proceed through a red light since they are unlikely to hurt anyone besides themselves... But the rule does kinda make sense. If there are lights that rely on car sensors then obviously fixing that would be the right thing to do regardless of the law.
I have a similar problem on my motorcycle. There are many lights which are not triggered by my being there. But the camera's always know. I wish they used the same loop / detector!
"Notwithstanding any other provision of law, if a driver of a motorcycle or moped or a bicycle rider approaches an intersection that is controlled by a traffic light, the driver or rider may proceed through the intersection on a steady red light only if the driver or rider (i) comes to a full and complete stop at the intersection for two complete cycles of the traffic light or for two minutes, whichever is shorter, (ii) exercises due care as provided by law, (iii) otherwise treats the traffic control device as a stop sign, (iv) determines that it is safe to proceed, and (v) yields the right of way to the driver of any vehicle approaching on such other highway from either direction.
