The traffic light timing at Cushing is actually fine; there are seldom if ever big backups there. The problem is that human nature causes people to be both selfish and think they're far more clever than they actually are, hence trying to beat the light. Slade is the same way.

Solution is to allow a contractor to dig it up, like they have the once whisper smooth Slade Street, which now has numerous dips, nicely disguised by asphalt but hit one at the speed limit and you'll bottom out, and maybe damage a tire, wheel, or suspension. try it on a dark, rainy night.

the light at cushing is ridiculously long
