Ok, I see where you say passing to the left of the runner is correct, but I still can't see having to move out into heavy traffic for the runners who refuse to move to their left. Fortunately, this is by far a teeny-tiny minority that are usually the iPod wearers or yakkers any way. Heaven forbid anyone interrupt their conversation for safety. Oh wait, I hear them saying an equal number of cyclists that do the same thing to them.
