I wrote in the previous post that red lights were the source of traffic congestion; then this afternoon I received my bi-weekly issue of Science News (aka “Reality Check News”).

Sidebar: The issue arrived via USPS a week or more late. One day last week I got two issues of The Chronicle of Higher Education on the same day. Sometimes I never receive credit card bills. Sometimes I never receive letters from editors and agents accepting or rejecting my work. Often I receive other people’s mail, including important tax and financial info. Why do postal workers get such huge pensions and then shoot up their places of work? Why do taxpayers put up with this?

An article by Rachel Ehrenberg titled “The Tao of traffic: Go with the flow” confirms my intuition and logic. In honor of Science News’s wisdom, I recommend you subscribe to it, if you’re interested in forensic science.
