Oh I see. Most of Australian cities are actually suburban and have had wider footpaths than necessary, as well as parking buffers. It’s trivially easy to just convert one side into a protected bike lane.

I still argue that in a lot of urban areas where the road has swelled to its natural limit, depending on the road, it can be good to reduce the road by one lane and add a protected bike lane. But this is situational. Not every road needs a bike lane. But there should be bike lanes every so often, so people can safely get close to their destination without bothering motorists.

It’s too much of a mental simulation to imagine how reducing car lanes becomes a benefit to those that must drive because of a reduction of traffic and potential improvement to overall flow.

Fair enough. Although reducing a road by a lane can improve congestion, it isn’t always the case, and isn’t a simple sell.
