More on the physics of panic stopping a TriMet bus (Yep, that's one lucky bicyclist)

Allen Morgan, TriMet’s manager of operations and training, sent me an explanation of what’s at play when a driver has to take evasive action to avoid hitting a bicyclist blowing a stop sign.“Stopping distance has three variables – the time taken to recognize the hazard + reaction time+ braking distance. We also have to take into account speed and road conditions.”
