But that is assuming that the guy going 73 isn't going to experience the same thing when he gets there. The guy who was stopped (or maybe even got lucky and arrived at a green light) is long gone before the guy going 73 has to face the same lights with the same timing. It might be marginally better for the guy going 73, it might be marginally better for the guy speeding or it might be a total wash. They both have to face the lights with the same phase timing regardless of how fast they were previously going and when they encounter the light.They're a choke point a person stopped at a light is going 0 and the person going 73 is still going 73 and catching up to speeder
We have all encountered situations where someone sped past us and we catch them at the light. We have also all encountered situations where someone sped past us and just made a light that we ended up having to stop for. Same thing here.
