Yeah, I have cars follow me into and through my neighborhoob fairly often and I WILL NOT go straight to me home until I know they are well away from me before then. In most of the cases it's been a resident a few blocks away that pulls into their driveway, but in some of the cases the people never seem to find their "home". In those cases I generally find a way to follow them until they leave the neighborhood.
I have standing directions with my wife and kids to call me if they think they are being followed and to lead the followers into a neighborhood close to ours. With my big F250 I can get in behind the followers and on the couple of occasions I've had to get involved I've scared the sh!t out of a bunch of kids thinking it was fun to follow someone (no weapons were ever presented). Their idea of fun changed once they realized that the game had turned on them.
I've also ensured my family knows where the local police precincts around town are located. BG's rarely follow you into the parking lot of a police precinct.
My wife used to always accuse me of being paranoid, but she's seen me proven correct too many times now. She's finally starting to see that once my "spidey sense" tingles, something bad is usually going on.
There are a lot of very bad people out there and there are even more just plain dumba$$es that get off on trying to intimidate folks while they are behind the wheel.
