On the way home from the grocery store a few weeks ago, my girlfriend was complaining about “all this traffic” and how our ice cream might melt before we get it in the freezer. “We’re part of the problem,” I said, thinking to myself how silly it sounds to complain about traffic when we’re contributing to the congestion just as much as the next driver.

In retrospect, I suppose we – all of us humans – aren’t just part of the problem, we’re the entire problem.

The clip above from YouTube user CGP Grey does an outstanding job of explaining exactly what causes traffic jams (it’s probably not what you think) and how a world that’s void of all human drivers will make traffic jams a thing of the past. It’s a fascinating watch that’ll really change how you look at traffic.
