Some clown in Germany got his knickers in a twist over the fact that the Google streetview car also scans and collects information on WLAN access points.
It is funny that when Google does this, it is considered an evil invasion of privacy -- but when volunteers do this in a systematic manner and then publish the data online it is suddenly a laudable collaborative effort. And it isn't like this is anything new.
The practice of wardriving has been a common one for the better part of a decade and today there are even apps for smartphones that turns your phone into a scanning device.
That horse has long since left the barn.
