bikes are allowed to operate as both bicycles and vehicles on public rights of way. I am allowed to use a lane of traffic, and i am also allowed to use a bike lane, wheras cars are not allowed to use a bike lane.
additionally I am allowed to pass stopped traffic by filtering, something cars cannot do.
bikes also have the benefit of using trails, sidewalks, unimproved grassy strips to theirt advantage, and not be riding like a 'car.'
bikes have more versatility than cars and can use more space of public rights of way than cars can.
Bikes have more rights than cars do, in my opinion, in use of public space.
