With Google Earth you can track right to the driveway, but if you look properly the scene is probably quite old, unless the satellite happened to be scanning your area the day before. As has already been said, if someone wants to find you they will. Same as all the call centres get your phone number, name etc. for cold canvassing, wether they are legitimate or scammers. Thanks to technological progress we are loosing our privacy, and maybe our sanity if we let it worry us too much.
