Where I live, there are laws mandating the minimum distance a vehicle has to be from a cyclist when passing (1.5m) - this distance is not covered by the available clearance in the cycling lane.
If you can't see a cyclist is in the lane, it's difficult to give them safe clearance, and driving as though you are always giving clearance to cyclists means driving closer to the other traffic lane, increasing risk of vehicular collision.
