I find this sort of comment fascinating.There's hardly any cycles on Boundaries Rd, why wd they need to go there when there's a perfectly good segregated cycle lane on the main rd literally metres away for them
My own experience of Boundaries Road is it's a nightmare for cyclists and there are a lot of us that use it.
However the drivers are awful as it's only wide enough for one car to pass. That means the cars feel that they have to get through when there is a gap but, even though they don't have right-of-way over a bike, they refuse to yield. That often means both bike and car are travelling down the same channel and if, as a cyclist, you want to stay out the "doored zone" then you have to ride right at them.
I've been hit twice on Boundaries Road, although it was only wing mirrors, and successfully reported five motorists for not giving way. I now often carry a D lock on my right hand when going up Boundaries Road and a wiggle of that towards a wing mirror makes a motorist focus but it's stressful.
But what I find fascinating is that two perfectly sensible people can have such differing views of the same pieces of road. The Balham cycle lane is great as long as you're going all the way to Tooting but if you want to hang a right anywhere passed the railway bridge, assuming you're going to Tooting, then you have to cross the whole carriageway and that is really dangerous.
I like the idea of these improvements but I'm not convinced they'll stick, I think that the traffic build up is going to be so bad that they have to rethink.
