I can imagine the meeting where this was discussed:
“We need to add a few kilometres of bike lane to keep the greenies happy. Put a white line along this road here.”
“It’ll be tight with two-way traffic, can we make it one way?”
“No, that would slow down traffic.”
“Well, we’ll have to take out the parking”
“Don’t even think about it”
Pity the poor transport planner. There is no way you can fit traffic in both directions, and a cycle lane, and space for residents parking on a road this narrow without someone getting the short end of the arrangement, and naturally you can’t expect Mercedes Man to drive a detour of almost a hundred metres to make the street more liveable. There are similar cycle lanes in this part of Stuttgart, including about a kilometre of lanes, broken by roundabouts every two hundred metres, where the cycle lane stops abruptly, spitting you into traffic, and then starts again the other side.
On the other hand, the drivers I encountered seemed quite used to a bike riding outside of the bike lane, so I guess it’s normal for them. Stuttgart also does seem to have worked out that a red cycle lane – which is equivalent to a blue lane in Denmark, and gives bikes travelling along it priority at junctions- is a good thing to remind motorists that cyclists have right of way, which puts them a few decades ahead of Ostfildern.

I wrote this before we moved and planned to post automatically, typically, not only did that not happen, but Karl at Do The Right Thing beat me to it with with a more entertaining version in Edinburgh.
