As for leaving the car exposed, I don't like to do that, but in my case I have little choice because of where my sinking spot is located. Fortunately, because it is along a secondary highway in an area with a lot of wood lots and hunting/fishing areas, and no cottages/houses nearby, people don't think twice about seeing someone parked on the shoulder.
There is some prime-looking sinking areas along the major highway near where I live, but I wouldn't dare attempt it... too exposed, and people will be dialing 911 to report your vehicle in a heartbeat. As much as concern for your welfare as it is concern you are trying to break into some place. Still would be hard to explain to the local constabulary.
Ideally, I'd love to find a place where I could park out of sight... but I make do most times. My car incidents this year are the very first time in more than 10 years this has happened to me, so I'm hoping it was a fluke both times.
With parking cars, I'd suggest trying to find a place which feels secure to you, even if you have to walk/bike a bit to get to the place you are checking out...
