I prefer MUPs when they're available - fewer intersections, less opportunity for a brain dead driver to take me out. But they aren't perfect, either -- plenty of brain dead (or iPod consumed) pedestrians not paying attention to other users.

Honestly, my second choice is well maintained, multi-lane streets; at least then I don't feel like people are crossing the center line to give me space, and risking a collision with an oncoming car. This isn't about 'guilt' - this is about lessening the opportunity for idiots to cause harm to others. Just last night I had a young kid in daddy's BMW come around me to the left on a residential street when I had TAKEN the lane. He was all the way across what would have been the center line, and actually in what is, from time to time, a parking area, all because he wasn't happy with my forward progress up a short hill. Honestly, I take the lane, there, to avoid exactly what he did -- most people aren't as dumb as he was -- because the line of sight over the hill is limited, and I don't want folks being on the wrong side of the road. I move over to the right as soon as I crest the hill. BTW: This is a residential neighborhood through street, with parked cars on both sides, barely wide enough for two way traffic, and where traffic really shouldn't ever exceed 25 MPH, and probably shouldn't exceed 15 or 20 to be safe.
