I must say, I go across this road at the crossing by the Copper Box twice a day and have done for five years, and aside from the occasional ignorant/impatient/whatever driver haven't had any problems. I don't even really recall seeing many buses or coaches along there!
I don't have problems there, either, but I'm still against building dual carriageways and the problems with motor traffic from far away coming off the motorway. It's not my own personal perspective, but a wide urban design/planning/traffic management perspective.
