I fully understand your own point, Mandy, and I respect it, but here is mine own.

I shall utilize a particular intersection that I pass through daily, Lake Otis and Tudor.

Let us say that I am traveling Eastbound upon Tudor within the outside turn lane to turn left onto Lake Otis, and I KNOW that at that time of day, there are 21 seconds of the green left arrow, because I can see the countdown.

Now, I understand that I have a set time to make it into, and through the intersection to make said turn with the light, but also KNOW that I am going to be three or four vehicles short of said turn whence the light turns yellow.

I take the foot off the gas, and begin to brake, as I KNOW I shall not make it, as the furthest ahead vehicle goes through the yellow to red light, and the one, or two, and sometimes more, vehicles goes through the already red light.

What am I to do, pray tell?

Become the second, or third red light runner, or actually stop at the red light?

Yellow means slow down
