(we've got Google maps and ultrasound detectors - what could go wrong?)

The [lack of] correspondence between various mapping efforts, and where
tube lines actually are, has been discussed quite frequently (on u.t.l
at least). Even when such a maps claims to be geographical, it often
merely relies on "joining the dots" (ie the stations).

A quick look at Google maps ought to make this more obvious, rather than
less, for example here at Ealing Broadway (the District being the most
egregiously wrong): http://goo.gl/maps/xDyNf

Curiosly the Google map does show, as faint lines, the real routes of
the lines. It is even worse south of Acton Town.

The lines on the base map look pretty clear to me, leaving the designers
even less excuse for the rubbish lines they have drawn. It's a bit of a
miracle they got the stations in the right places.
