Switching lanes in dense traffic does reduce flow and increase everyone's commute time. Cutting across a couple of lanes, exiting the road and then merging back in a few blocks later is even worse. If more people thought of driving as team-work rather than a race we'd all spend less time in traffic. This fellow argues that behavior that slows traffic down is a good idea because if makes him feel good. I'm sorry buddy, but you're an idiot. You're taking actions that do not benefit you and harm me because you lack the mental discipline to relax and stop treating traffic like a race.
Here is a suggestion for those of you who are currently like this guy but are willing to try driving smart for a change: Don't alternate days. Get into one lane and stay there and continue to do so for a couple of weeks. Listen to the radio. Think about stuff you need to think about. Zen the #$%^ out. Once you unlearn your moron-driver habits you'll arrive at your destination a lot less stressed out and you'll have the peace of mind that you're not one of the morons adding to the problem.
