Those tracks, and the many more electric trolly car tracks around town, are a real hazard for any two-wheeled vehicle and get very nasty when wet. But anyone riding in SF for very long tends to learn how to cope.
And usually we learn the hard way! Like turning hard on a ST1100 with sketchy Bridgestones at 17th and Church, across multiple tracks that, in hindsight, turned out to be covered with motor oil. Dam that bike was hard to lift back upright!
