When I was on a trip, I saw a light that went directly from green to red. No yellow. Of course, it had a red light camera on it.
If this were deliberate, this is pretty nefarious. It would make good money to have the yellow just not operate every 1% of the time at random, and there is no way it will ever be caught (the camera will show the red light and the person through it 100% of the time) unless the victim has a drivecam which was recording the light's actions, and there is some iron-clad proof that the drivecam's time was accurate.
