It's still that way. The roadspace isn't analogous with train tracks or airport runways where there is one exclusive user. The reason we have traffic lights, stop signs, HTA rules and layers of by-laws for automobile users is to ensure pedestrians, cyclists, people on horseback, etc. can safely use the same roadspace.Originally, the legal rule was that "all persons have an equal right in the highway, and that in exercising the right each shall take due care not to injure other users of the way."
What's changed is that we generally don't care about each other anymore while assuming absolute ROW in contradiction to commonsense survival instincts. Otherwise why would anyone simply walk in front of moving cars, regardless of their ROW. As a motorcyclist I assume that everyone, from the truck behind to the unleashed dog on the sidewalk is a risk to my life and I act accordingly. Same goes when I walk on the sidewalks, I assume and then manage the risk. If I walk across a road outside of a controlled intersections, well, my safety is on me, since the system has already accommodated my needs by providing the controlled intersection and crosswalks.
