Laws should be written in such a way that if everyone follows them the road system functions properly, not trying to manipulate people by putting up a stop sign when a yield would do. Putting up stop signs everywhere has had the perverse effect of making stop sign compliance very low -- even at intersections where it is imperative that they be followed. Now we have graduated to stop lights everywhere because road-users still comply with those, but that's going to change if they keep proliferating.
I've come to the conclusion that nobody knows the law, they are just running around looking for things to be angry about. I see plenty of motorists brake-checking each other, I suspect these are the same self-centered individuals that run stop signs at speed on their bike and brake-check other road users.
