Of course, there are also places where the risk is higher. SF is just an example used because someone prominent died in SF whilst on a bicycle. The easiest thing the USA could do to make cycling safer without investing a cent in infrastructure is to adopt the rule that by default if a car hits a cyclist the car is at fault. The effect of that would be instantaneous, every bike would have an invisible force field of liability around it. Sure, some might abuse it, but nobody in their right mind is going to play chicken with a car.
