Bicycles are traffic.
A bike in the lane is a vehicle in the lane. When it sees the need to, even the slowest bike can use the full lane. Bikes slower than other traffic can use the full lane to pass, to turn left, to keep from being cut off at an intersection, or if the side of the street is unsafe. Sharing the road takes respect and patience. Motorists and cyclists need to share the road with generosity and responsible treatment of each other.
