Of course the problem comes on scenario 3 where the light stays green, and now you're back on the gas as you enter the dilemma zone. It would be nice if there was some standard of say minimum 5 seconds more green after 0 if 0 doesn't mean yellow. I think it's pretty rare that it's like 2-3 more seconds, but I feel like that's happened to me a few times and is very annoying.

The problem is people in the option 2 scenario chose to coast in when if they had continued at speed would have safely made it through the intersection after entering the dilemma zone. Thr timing of the yellow and Red/Red phase has already allowed for people going through the intersection on yellow.
I agree in the no chance scenario or speed up scenario it could help. However I think the practical application is that people slow down early rather than entering the intersection on yellow. This reduces through put.
