This will have to do with the fact that the number of cars using this street is relatively low. Because although it is a main route for cyclists, it is not a main arterial route for cars. For motorised traffic this is just a 'neighbourhood connector road'. Meaning it serves as the access road for a particular part of the city but it does not provide a fast through route for cars that need to be in a different part of the city.
|The remaining car lanes are narrower than the cycle lanes.|
|The street (in black with arrow) is just a tiny fragment of the city's main cycling network.|
