Re: Common sense
I don't think enabling a feature like this it will produce a circle centred on the house since people leave their house along one or two routes, unless they live in a featureless desert, rather than travel out in a random direction each time.
The circle needs to be big enough, though, say a few hundred metres, to encompass many houses. It also needs to be big enough so you don't have to give the exact location anyway, since a copy of the database may be sold on when it is eventually stolen.
