Well, see this is the thing, I did say that but I didn't feel all that kettled tbh but I think that was due to the crappy implementation. I used to live over in Peckham on a street that was blocked and you had to go completely round the houses to get anywhere if you weren't on foot and I thought it would be like that, which was a little like being in a locked room that you can't escape from, it was one of the reasons I moved. But in that instance the road was completely blocked, not left open for buses etc.
So no I didn't feel less kettled yesterday or this morning but interestingly I also haven't seen a massive rise in traffic yesterday or today down LR so maybe the closure did do some good and get people using methods of transport.
