Traffic controlled stop lights..

[Oldgunner]

Relatively new to scooting, so I am not sure whether I am guessing correctly or not, but here goes.
I often come upon those traffic lights which are controlled by a car parking where a sensor changes the signal from red to green. I may be wrong, but I think some of those don't trip for scooters. I have waited long for some and even gave up on some, and just turned around and took a different route. Have you ever had trouble tripping the signals with your scoot?
