Both junctions are very dangerous. Yes, the Devonshire road exit can be seen clearly but only for a short stretch and only if the road is clear ahead of the approaching vehicle, which is not often the case on the South Circular which not only has a high volume of traffic but especially has a high proportion of trucks and high-sided vehicles.

Yes, this does happen, but also from traffic turning right from Devonshire. Maybe fewer would be trying this manoeuvre if the lights from Honor Oak Road into the South Circular remained green for a couple of seconds longer.
