I used to walk across SF on a daily basis and I would usually go out of my way to avoid certain streets. Some because of homeless people/blocked sidewalks, others because of hyper-aggressive traffic. I'd happily add 10 minute to my walking commute just to start my day on slightly more pleasant streets.
