I think you wouldn't have to go that far, even things like identifying traffic lights would be a lot easier if you had an up to date list of their locations. Worst case I can think of are car accidents where the people involved have to place warning signs on the road and construction/cleanup crews that are slowly moving along the road, but that would still be a limited amount of exceptions to handle instead of trying (and failing) to handle everything.
