It'd be
"lights out and away we go" at any intersection with a countdown for red. Drivers start moving about a second quicker, studies say... wouldn't take long for the all-red time to be upped by a second to negate the advantage.

Of note is that many jurisdictions from a cost-benefit perspective see very utility to significant dilemma zone mitigation measures in urban areas with lower speed limits. 60 kph is generally the threshold.
A better solution is something like this, where the traffic signal gets smarter and tries to snipe a perfect moment to changeover by monitoring the speed of each vehicle approaching so that nobody gets caught.
