In law, the pavement (the legal term is "footway") is part of the road (legally termed "highway", generally comprised of one or more "carriageways" plus whatever "footways" the highway authority deem necessary and/or desirable). RTA 1988 Section 192(1) , HA 1980 Section 66(1)
So your clarification makes more sense - thanks - but is technically incorrect. Turns out so was mine (as my edit clarified). But I am still mystified that anyone would see a runner coming towards their stopped car, look the other way, and then assume it was safe to drive off without checking again where the runner was. I suppose that the OP, for one, will not make that assumption in future ;-)
