 October was a tragic month for the Oakland community in Pittsburgh. Two pedestrians and a cyclist were killed in car crashes within four days of each other. While the collisions are still under investigation, I have a strong suspicion that speed was a major factor in both. The survivability of a crash decreases very dramatically as speed increases from 20 to 40 miles per hour [1].
