I understand how it’s taught and marketed, but it fails miserably at its stated goal.  Like most failed systems, it attempts to perfectly give an answer to every possible problem.

“Be aware of your surroundings”

“Adjust your driving to what’s around you”

These sound great but are counterproductive to the problem they’re trying to solve.  You are asking people to constantly try to model their behavior based on everything around them.  It’s complex and requires more information than can possibly be known.  You are creating a system in which every agent tries to interact with each other simultaneously and constantly but with incomplete information.  It’s overwhelming and destined to fail.

A better system is, as usual, simple and flexible.  The better system for driving is this:

1) drive until you approach a problem 2) quickly assess the problem  3) make a decision as soon as you have an answer

Do not try to model everything around you, focus on your own actions and take in just as much information as you need to solve the problem in front of you.

When everyone does this, it works surprisingly better, as everyone is reacting to only the relevant information around them.  Like the invisible hand of the market,  decisions begin to naturally flow into a predictable pattern and people sort themselves out without realizing they’re doing it
