Not even true. I've been hit by a car (with human driver) on a sidewalk. Driveways cross sidewalks, and drivers seem particularly inattentive when crossing them. When you're walking on the sidewalk, do you ever walk somewhere that's more than one block away? If so, you're going to have to cross a street anyway.
