The european cities have a problem with roads not broad enough for cars. In a city that have broad roads that fits more than four car lanes, you can easily split one lane off physically from the car road and make it into a two-way bike lane.

When the population are used to this and the car trafic goes down, the bike lane will be too crowded to be a two-way. Then you do the same on the other side of the street and make them both one-way roads with car lanes in the middle.

In our town they are rebuilding the bus stops on streets so if two busses stop, they will block the whole road for car traffic. The bikes can pass on the separate bike lanes though. This by design so people will choose bike instead of car. Not quite thought through though since this will also block blue-light traffic...
