If you go through the vehicle code with different color hi-lighters, using a different color for each class of user (car drivers, truck drivers, motorcyclists, equestrians, cyclists, pedestrians, etc.) and mark each section (each law) with the appropriate highlight color if that section applies to the associated class of user, then you will find, with few exceptions, that a large set of them that apply to car drivers, truck drivers, motorcyclists, equestrians, and bicyclists, of which none apply to pedestrians, and a set that applies only to pedestrians. That's what I mean by two sets of rules.
Of course there are vehicle-type specific exceptions. But, by and large, there is a set of rules that applies to ALL drivers of ALL vehicles, including bicyclists, and it is that set that is the legal manifestation of the vehicular rules of the road with which VC is concerned.
