Yes, there is something worse. I recall back in the mid-80s when I lived in SoCal (Vista CA, which is just south of Camp Pendelton in San Diego County). CA Hwy 78 between Oceanside and Escondiido was 25 miles of hell due to only having 2 lanes each way, so 1 asshole in the left lane could cause a 25-mile backup (and did, every single day). In the lead-up to adding a third lane each way, the Escondido newspaper had an interview with one of the local CHP officers. In that iinterview, he specifically called out what he called "amateur traffic cops" and told them to get out of the way and into the right lane because they were causing traffic hazards. And he didn't care if they were "doing the speed limit". He's right, those who get in the left lane in order to try and regulate the behavior of others are asshats who cause accidents. And anyone who decides to punish a tailgater by jumping out of the left lane at the last second in order to cause an accident should be held liable for all damages to all cars and people who get injured due to their ass-hattery.
