> yellow must mean "begin controlled deceleration immediately"
This is not true in the strong form you used. There is a regime where there is no possibility you will be able to stop the vehicle in time using reasonable deceleration. Slowing does no good. There is also a regime where slowing will cause you to enter the intersection during the red light, and not decelerating will not.
That's ok. We can hammer out the details together, but the principle is true if the light turns yellow before you reach the intersection. Note that I didn't say how rapidly you need to be decelerating, and if the light has turned red before the car even clears the crosswalk, as is the case for the first car, then the driver sped up instead of slowing down.
