Common sense suggests that the cycle lanes may be sort of flexible and driven over at narrow bits if there is no cyclist ahead, however, should one be seen, then hold back and give plenty room – what’s the problem?
Edit - Having said that, I have no regard for the design of the Gowkley Moss roundabout, with its crazy tightening up radius curve going south and its lane funneling going north - illogical nonsense. People study for years to become highway engineers, then produce crap like this, but it must be checked by some bod at the top before spending hundreds of thousands, you'd think.
Another edit - Don't mention the camber!
