The London Underground is actually kind of a dumb use-case because it’s fixed infrastructure.

On the other hand it's a perfect test bed, because there's sufficient changes of direction and speed, and the fixed infrastructure lets you measure drift. Plus it being underground helps simulate GPS signal being weak or unavailable.
