All that is required to “fix” the monolithic logjam on Los Osos Valley Road that begins at the entrance to Costco and Target, is nothing more than using a teaspoon of common sense. Until this corridor can be enlarged, simply set all the lights at those intersections all the way down and over the freeway and include the exit light at the entrance to Highway 101 to two minutes. This will allow the cars in both directions to move quickly and easily.
But hold it, folks. I forgot to mention that this is much too simple of a solution, so it will probably be given the thumbs down.
