So the question is how on earth do they map those to lat/long, and they
must rely in great part on people basically wardriving. Detecting the
same access point in a couple of places, together with the relative
signal strength at each place, must give a reasonable approximation to
its location.

But it is still quite surprising that they've obviously driven down my
street.

Or they get a MAC address to street address mapping per customer from
the ISPs...
