"Bike Lanes"

So. . . there are "bike lanes" now on Chestnut (going south) and Keswick (going north--this according to a tipster; Hawker's been too full of Christmas cheer to check it out herself.)

Thing about these "bike lanes" is that they're not bike lanes! They are big pictures of bikes with arrows indicating direction (north or south) painted on the street. . . in the car lanes. Hawker is not sure how this makes things safer. Does this mean you can only ride your bike where there are pictures of a bike on the street? Cyclists: please explain!
