I have a unique perspective here, having lived in both Australia and a modern European country with AMAZING cycling infrastructure. Bikes should not share the same spaces as pedestrians OR cars. Period. If they
must share, bikes are much closer to pedestrians than cars, yet we ask them to share the road with cars. These modes of transport are VASTLY different, and of course lead to all kinds of animosity between these groups. Australia is notorious for underfunding and ignoring anything resembling cycling infrastructure. Cyclists believe they're "motor vehicles," and indeed, under many statues, they are legally classed as such. The problem is, when there is a 20 car queue stuck behind two cyclists riding next to each other, cruising along at 30kph in a 100kph zone (yes, this actually happens, often), this just not efficient use of the road.
The answer is not "teach drivers to be okay with driving at 30kph everywhere." That's silly and I'm tired of this canard. The answer is of course better infrastructure. Hard barriers between cyclists and motorists, and preferably pedestrians too. The only reason this problem exists is apathy and greed. It's often the motorists most impacted by slow and dangerous cyclists who are least willing to increase their taxes to solve this problem.
