Let's say you own a motorhome/caravan and it's kept on your drive. To determine whether you are away on holiday or not, all I need to do is drive by your house and compare what I see with what Street View shows. I can take a 2hr drive through suburbia and draw up a nice list of homes whose residents are unlikely to be in when I come by again in the evening.
