As Google Street View cars passed by recently, they not only collected geolocation data and pictures of the streets, but also recorded information received from wireless hotspots. Google collected data not just from public wifi locations, but from private individual’s wireless routers as well.

Google is well known for their “Google Labs” and “beta” products, but usually you must opt-in to get access to these features. Unfortunately for some google account holders there is a test being run on google search that there is no apparent way to opt-in or opt-out of.
