The biggest hazard to a cyclist riding on a sidewalk is the cars.

Pedestrians and cyclists don't pose much threat to each other. The problem is when the sidewalk crosses an intersection, the traffic moving through the intersection isn't expecting something moving so fast. At a walk you can easily change direction or stop, anything faster, not so easy.

I have a friend who was jogging on a sidewalk with her dog when she was hit by a car. SHE looked--the driver didn't. Her dog was fine.
