It's amazing what people will adapt to. A friend of mine living in Minneapolis said you can't lock your car in her neighborhood, otherwise someone will just break the windows to get inside to look for things to steal. One night, her husband forgot and locked it out of habit, and before the next morning one of the windows was broken.
There is no perfect place to live. Everywhere has trade-offs, and I bet we could both come up with 100 things more important to our quality of life than whether you need to lock your car door or not.
That anyone chooses to live like that baffles me.
