Except that it is in no way equitable, if passenger vehicles are effectively blocked from making turns. That is the result of failure to enforce the laws against pedestrians illegally crossing streets. If pedestrians followed the rules there would be a remarkable drop in downtown gridlock, which would also enhance pedestrian safety.
Drivers who were required to have a flagman walking in front of their car might take issue with your "since the advent" comment.

One that sticks out for me goes back to the recent introduction of the one metre rule for passing cyclist. In the particular news cast I was watching, the officer explaining the new law set up a pylon 1 metre from the car and said "this is a safe passing distance".... Okay, fair enough I thought... Next, they started to talk about 'dooring' a cyclist and proceeded to open the door . When the door fell well short of the pylon marking a safe 1 metre passing distance I couldn't help but wonder why cyclist can't be responsible enough to pass stopped cars at a safe distance as well. This hardly seems 'equitable' to me
