But what your doing is mapping one concept on to another. Stop signs and stop lights are different. The only times they should be considered the same is when the lights are totally out or when they're flashing red.

Creating the mental equivalency means more confusing of you come to an unfamiliar road layout. Plus your left on red of one way when explaining it becomes is that one way to one way, or one way to two way or two way to one way? Then you're juggling these concepts and (maybe not you) but people will make mistakes.

When you distil it down to a simple concept of turning on red is allowed when you don't cross a lane of traffic, none of that mapping of one way or stop signs is needed. We only need one other fundamental driving concept of what a lane of traffic is.

Although I will admit it seems that some people don't know what a lane of traffic is.
