in my mind this means anything from avoiding a hazard to doing what feels right to me personally. for example, I ride on a sidewalk during my commute. alongside a very wide well-paved street that I could easily cycle on... not very vehicular, but it is more pleasant to me than the street as it is shaded and planted with flowers and has lots of trees and grass and birds, etc on either side. rarely have I encountered peds here. most people are in the offices, working.
