Congestion conjecture.

Every morning, the tollway is packed. Exactly when it's packed is fairly consistent, and frequent tollway travelers know when it is. They plan for it. They need to get to their destination at a particular time, and they leave at an appropriate time.

Most people need to get to work at about the same time. Most people need to leave the tollway at about the same time. The rush hour always ends at about the same time. It just evaporates. Everyone jamming the road has gotten where they're going, and they all exit at once. Morning rush hour will always end at the same time.

Morning rush hour will begin progressively earlier. As more people jam the road, people have to leave ever-earlier to get to work at the same time.

Lately my daily commute has stretched to a total of 2.5 hours per day. I don't spend a lot of time thinking about the nature of the congestion, but I do think about it often.
