No, just the nasty bits. It's a false dichotomy to pretend that we must have protected infrastructure everywhere or it must be nowhere.
No more false than the contributor that suggested, in quite rude terms, that the behaviour of motorists could not be modified.
And what's a nasty bit? It's errant motorists that make roads dangerous, not the roads themselves, and danferous drivers can strike anywhere, any time.
And traffic flow, usage, and driver behaviour are constantly shifting. What might be a nasty bit today may not be this time next year. Just up my end, changes to a busy roundabout in March has caused a radical shift in usage patterns, favoured routes and driver behaviour, and the existing segregated infrastucture (theres is some, as crap as it is) is now suddenly redundant, and where it might
now be needed there is none. It's not physically or financially practical to keep chasing changes in road development by continuously playing whack-A-mole with mallet of new segregation.
And there's the elephant in the room, the one about there being little evidence that cycling infrastructure makes a NET conteubution to rider safety in the UK and
may actually have a higher casualty rate than the roads. Thats difficult to quantify for sure without much more research and analysis, but the little data that does exist is sufficient to support genujne doubt over that matter - this requires investigation. As we know, doing something blindly in the name of safety rarely makes us any safer and often actually increases the risk.
The simplest and most cost effective solution is to tackle the problem at source. No cost to the exchequer, no issues of planning or practicality, and no issues with getting left behind by the ever changing ebb and flow of traffic. Sadly that's also the politically most unpalatable solution because motorists form a significant voting bloc.
