What is a potential issue with traffic-activated sensor lights for motorcyclists?

Traffic-activated sensor lights are designed to detect vehicles waiting at an intersection to change the traffic signal, but one potential issue for motorcyclists is that the sensor may not effectively detect the motorcycle's presence. This is largely due to the smaller size and lighter weight of motorcycles compared to larger vehicles like cars and trucks, which the sensors are often calibrated to recognize more easily. If the sensor is not triggered, the motorcycle may be stuck waiting at a red light, leading to frustration and potential hazards if the rider decides to proceed through the intersection without a green light. Understanding this issue helps motorcyclists be more vigilant and aware of their surroundings while navigating intersections with sensor-activated traffic lights.
