What cycle lanes around town are not "actually fit for purpose"? Reason I ask is they're not currently of use to motorists, so if they're not fit for cyclists would you be in favour of them reverting to part of motor lanes?
As for ambling pedestrians - given the amount of cyclists cycling on footpaths it's more than a bit rich for cyclists to be complaining about the odd pedestrian walking across the cycle lanes.
Cyclists should be told "Either use the cycle lanes or lose them back to motorised lanes for good".
Too many cyclists are looking for confrontation on the road with their "I'm perfectly entitled to cycle any way I feel like it, and irrespective of whether or not there's a cycle lane or not" attitude.
