Reverse Wardriving in the Bay Area

This article is fascinating, and an indicator of just how difficult it can be to keep information secure in this day and age. To nutshell it: a guy in the Bay Area has used his wifi apparatus to track bus throughput and identities for corporate commuter buses from Google, eBay, and Apple that pass by his home on a daily basis. He's even corroborated them with unofficial maps floating around on the Internet that document these companies' bus routes. (As noted, this is the reverse of "wardriving", which is the term for driving around looking for accessible wifi hotspots - in this case, the wifi hotspots are coming to him, hence "reverse wardriving".)
