I think that’s probably quite a selfish world view (and also quite arrogant to claim your own view is hard to argue against - of course you would find it hard to argue against, that is moot…)

When there is infrastructure to support all 3 kinds of users, it seems a lot more equitable for everyone to use the space cooperatively.

I absolutely agree one should give way to more vulnerable road users, but that all 3 can have better outcomes (safety, speed of journey, efficiency etc) it all use it cooperatively and conscientiously.

To labour the point, on shared cycle and pedestrian paths with a line down the middle, does a bell ring combined with slowing down to a safe speed not seem like an appropriate warning?
