if you’re in central London and want to go from Covent Garden to Leicester Square, you might think of jumping on the Piccadilly line. But, in reality, the distance between these two stops is just four minutes on foot. Conversely, if you’re going from London Bridge to Borough (maybe to check out the food market), then the official map makes this look like quite a sizable distance. Should you take the tube? Nope, because in reality the two stops are only a nine-minute walk apart.
