All of these issues are systemic issues and a failure of infrastructure. It's fine on an individual level to say that riding on footpaths isn't ideal, but ultimately people are going to do it no matter how much you call them out for it, if they feel it's the safer option than riding on the road. So if you don't give people a safe option to ride their bikes, then they are going to have to pick between multiple unsafe options, which is not ideal when you are trying to drive an uptake in cycling. And the most important way to make cycling and walking safer, is to increase their popularity, because it means there are less cars, and cars are a much more serious threat to pedestrians.

Anyway, we are probably talking past each other a bit. I think that in the end you are talking about sensible individual choices (which is fine), but I feel that the majority of efforts and discussion need to be directed at governments if we want to make cycling so safe that even a 5 year can ride around unsupervised.
