Where I live over 50% oh households turn off their routers when they are 
not at home and at present I am staying at relatives, about 200 miles 
north of where I live, and that figure has increased to about 80%. I 
would also say that with people changing their ISP options and 
consequently their SSID's, most people never change their ISP's unique 
SSID's but everytime the router or ISP is changed the SSID changes, 
that their has been a 40% change in the last 18 months and I doubt 
Google are going to renew their database that frequently so I am not 
convinced about using consumer wifi as a location device in the UK. It 
would probably work with wifi hotspots which tend not to change and are 
near to your "fish and chip shops" but I see no reason for them to be 
recording wifi networks on housing estates which are a couple of miles 
away from anything.
