The basic idea of CFI is.....
People on 3500 South have the green, you'd just be sitting in the left turn lane waiting for your turn, so why not let you cross Bangerter into a collector lane? It's red on Bangeter anyway, and nobody's going to be there except a few people turning right.
Then once you are in the collector road you can then freely turn left while Bangerter has the green. You'd still be waiting for the light regularly.
I think it'll work, but I must admit I'm worried about how people will figure it out. I hope it's pretty clearly laid out, like the SPUIs.
