A danger of valet parking. Or anything similar where you have to give your car to someone to park it. If you have a GPS system in your car and your home address is set in it. Someone can easily look it up, take a snapshot of it and use it as they please. Including for a home invasion. Always program your home address as something else. It can be anything. Just don’t make it too obvious as a fake title. For example, it can be titled as “Joe’s place” or something like that to make it vague. Best thing would be to avoid programming your home address into the GPS just to be safe and type it in every time you need it. It doesn’t take much time to do so. Practicing little safety measures like this one can have long term benefits.
