I sat on my scooter for two light cycles and the left turn arrow never came on even when a car sat behind me for one of them. I finally moved forward and sat in the pedestrian crosswalk and the car behind me moved forward. Not sure whether there was another car behind him or not but it finally triggered on the third cycle. The pad is either too far forward (see how it's past the stop line?) or too far back. Or it's just not working.
