This would only apply if we had no other method of determining location.
If we use passive beacons or Vision or something else thaose can easily
provide the "boundaries" needed to keep us out of the street.

We will have to have at least one method to find where we are that does not
rely on physical boundries (like between my yard and my neighbors) If we already
have one method of finding where we are that can keep us out of trouble I don't
see why we need another. We are working to a budget sort of.
