We have a few places where an MUP crosses city streets, here in the Salt Lake valley. I'm always surprised at how good the car drivers are at yielding the right of way to bikes and peds. I was just stopping to wait for a car which was almost at the intersection today, when he slammed on the brakes and screeched to a stop. I would not have stopped had I been that close when I saw a bike. On the other hand, at the intersections with lights, I have seen several motorists blow the red. Go figure.
