I have also been stuck trying to turn right at that junction, I was stuck in the box and had to reverse back as cars went around me. It is especially hard to do it when theres a bus in opposite direction trying to turn left, not to mention how dangerous it is as you can't see cars coming from behind the bus. One has to be watchful of the oncoming traffic going towards lordship lane as there is a tendancy for cars to go through the Red light, which usually cuts off people wanting to turn right. Similar to the Camberwell Green crossroads, the filter light for people turning right towards Peckham, has made an insane junction work.
