I agree (US perspective). The doctrine of verifiability is overdone; the point should be that a normal mapper has the ability to verify, not just things that are visually apparent. In the US, the notion of motorway/primary/etc. is messier, as it's a force fit of UK norms. In my state, speed limits are, unless otherwise posted, 50 mph if divided, 40 mph if not divided, and 30 mph if "thickly settled". There are often yellow (advisory) signs that say thickly settled when coming to an area where the police want you to think the density exceeds the thickly settled definition. For map speed limits to be useful, they should definitely be tagged explicitly. Overzealous declining to tag because of an extreme definitino of verifiability does a disservice to users.
