I'm not worried about that, but I've seen some more cautious people get the cable underneath one of their wheels so that you'd have to move the car to take it. I'm quite sure you could also find another way of attaching or securing it to your car to make it fairly difficult to walk away with. The chargers also aren't really worth much, so it seems unlikely that even someone desperate for cash would put much effort into it.

It helps to have your own home, and my area doesn’t have much vandalism

My charger is not detachable and is not especially valuable in itself, so I think of it more as vandalism than theft. Someone might vandalize my charger for the metal in the cable, I guess, but I also have an air conditioner compressor outside that I’d expect to be more valuable, if harder to walk away with. As a property owner, there’s always something that could be vandalized or stolen, but you need to balance your costs and convenience with what you expect from your neighbors

R u so paranoid that u think people are gonna steal it? I mean it might happen but I live in quite a rough place and I wouldnt even be worried abt that

That's a problem that is pretty easily solved. It can all be solidly affixed to the wall, locked to the vehicle, etc.
