Presto, you have "life saving traffic control". Hey, it works in Chicago...
Fortunately, I think the fad has already reached its peak in the US. I suspect places that don’t already have them will not have them - at least for the foreseeable future.
Here in KY we mitigate the risk by having a three second delay between the time one light turns red and the other turns green. In some locations, it’s six seconds - Three seconds before the walk sign goes white and then another three seconds before the traffic light goes green.
I can time it to get an early start and easily beat other cars off the line if I have to merge in fast. :)
