Similar thought, but in cities, I'd prefer to cross major streets and make left turns at signaled intersections. I might save 2 minutes on my 30 minute commute, but those are incredibly risky and stressful maneuvers. I use my GPS because it has saved me from an hour of traffic more than once, but I don't need to risk my life to save 30 seconds.
