You don't know that they're not attempting to travel into your path. Once they ignored the rules of the road and became unpredictable, you need to treat them as possibly doing the stupidest thing for the given moment.
Many a time I've come up to a stop right after someone else, and they start waving me on. But almost invariably, unless I immediately go (basically without even waiting for the 'go on' wave) they will wave me through, and then start driving through the intersection.
The point is these 'go on' people _are_ ignoring the laws about when a driver must yield. They're trying to tell a driver that must yield that its okay if they don't.
