That bit is obvious; but like fatty, I though you were 'supposed' to give way to someone waiting. Reason being that the pavement is still part of the highway, so if you're leaving one road to turn into another, then you need to give way to another user of the highway going straight on.
Seems that that wasn't the case, unless, as I said before, it was only guidance.
Either way, if pedestrians start walking straight across without looking becasue it's their right of way, then folk are going to get hit.
