I think if two key driving skills were taught, traffic would be greatly improved. The first, efficient merging, which means, no, you don't stop in your lane to move to the right, you speed up a little and leverage the accordion effect of the slower traffic on the right to find a spot big enough for your car to fit in and then merge. More efficient utilization of the space on the roadway, while keeping the lane you're leaving and the one you're entering moving at their respective speeds. Second, speed up when you get out in front of the jam. This is well studied and found to mitigate the traffic jam behind, when enough drivers do this.
