I think somebody else said it best “whatever makes you feel more comfortable, then do it” .. so if you don’t like having your home address programmed into the Nav system then that seems reasonable.
However, I do think people imagine these elaborate scenarios with regards to crime, but give very little thought about the things that are far more likely to happen. Typically crimes are ‘opportunity’ crimes.. if it involves more than one step (think rock through a window of your house) and a couple minutes, it’s not going to happen. If somebody is going to go through an elaborate process to rob you, then you are being targeted and there isn’t much you can do to stop them if they’re that determined.
It reminds me of conversations with my mother-in-law about how sleeping next to a clock radio will kill you, but she still doesn’t wear a seat belt (true story).

I’m not sure I made my point very well with my example, my point was if people spent a proportionate amount of time worrying as the level of risk, then they would never leave their house.
Bottom line.. don’t worry so much.
