Valvegrid, war-driving still goes on and if your WIFI router is broadcasting its SSID then someone in a car across the road will know you have a WIFI network. I travel around a lot and the amount of networks my laptop picks up (including local council ones) is amazing. They are using WEP encryption but lots of people don't. They also don't change the admin name for the router either.
through the City of London, or the West end come to that, and id you know what to look for you'll see warchalks.
As for war driving - I can think of better ways of spending time, but it does still go on. I doubt that there's anything like the amount of it that some people would have you believe, but they're out there.
Following Cardiff Council, which last May became the first city council in the UK to offer its residents free wireless internet hotspots, Preston City Council last week announced it has installed wireless networks across its centre in a bid to broaden computer access to residents.
Initially, the council approached the University of Central Lancashire (UCLan - click here), which had already set up a wireless network over its two campuses at Lancashire and Cumbria.

Could this mean that in the future residents will only need a receiver to pick up the Internet and not have to sign up to an ISP?
