Traffic Pileup

By a stroke of luck, I got an excellent video of how traffic jams start. In this movie the cars start to pile up, I went around them, and noticed that at the head of the traffic was a pair of cars going about 55mph. The remainder of the cars couldn’t get out from behind them because they needed to get off at the next exit. Had the traffic been slightly heavier, the jam could’ve stretched for miles and led to bumper-to-bumper traffic.
