> We are grateful to Enrico Moretti
If I'm not mistaken, that's the same Enrico Moretti who wrote The New Geography of Jobs, which is a fascinating look at the economics of cities that are trying to attract jobs, as well as a paper on how zoning restrictions cost the US economy billions of dollars a year by keeping people out of productive places.
Edit: Tom Scott has a video (somewhat theatrically titled "Lies on the London Underground") that highlights some peculiarities of the London Underground, some of which are (partly) caused by the non-geographic nature of the maps:
But, if what you really care about the physical locations, there are tons of other maps that you can use. Subway maps try to preserve some correspondence to the physical world but that's not their primary function.
Otherwise you end up going all the way in and out of town and missing the lovely views, or waiting 10 mins for an overground train when you could have basically been there by now.
