A Swedish physics study has determined that there is less of a risk of a traffic jam if a significant fraction of drivers break the rules and drive like jerks by doing things like passing on the wrong side or changing lanes too close to an intersection. The study determined that the risk of traffic jams was lowest if 40% of drivers drive like jerks.
We doubt this study because there continue to be traffic jams in the Bay Area.
