One of the things that intrigues me about commuting is the randomness of traffic patterns. For some reason, traffic was much heavier on my route yesterday, both riding to work in morning and home in the afternoon. I left about the same times as usual and followed my typical route. On one neighborhood street, where I usually encounter few cars, I got stuck behind a long line of them at a 4-way stop. On another neighborhood street, traffic was backed up for several hundred yards in the left lane for cars turning left at a signal, but there was not a single car in the right lane. Fortunately I always take the right lane at that light so I breezed right by all the cars.
