If they have bikers shorts, helmet, calves the size of watermelons, then they usually follow the rules extremely well. It's the ones who use the road and vehicle laws until they get to an intersection where the lights don't meet their needs, they pop the curb then use the sidewalk and start using pedestrian laws.........can't do both, it usually doesn't turn out well.
With those Spandex shorts and shirts a lot of them resemble three-gun shooters.
You can usually distinguish between the two by waist size though.
