Cyclists are tough to predict. They’re small, can reach speeds of 30mph or higher, sometimes break traffic laws, may or may not use bike lanes, split lanes and weave between cars, and can change direction far more quickly than vehicles. Our vehicles encounter cyclists 16x as often in SF than in suburbs, so we’ve invested considerably in the behavior of our vehicles when a cyclist is nearby. In the video below, we narrowly avoided a cyclist in all black. He made a sharp left turn across traffic without having the right of way.
