Over the past year or so, we've done a lot of hub-and-spoke tours where we drive out to a spot we deem our headquarters, and then we ride out in all different directions over the days we're there. In those cases we leave the car at our cabin or campground.
I imagine you could leave a car parked in a residental street somewhere for a week. When I lived in Edmonton for a semester, I would drive up to Edmonton on the Monday, park my car on the street somewhere near the place I lived, and then I wouldn't touch my car again until Friday when I drove back "home" again. No one bothered with my car for those days. If a person were to leave a car in a place like that without using it or moving it for a month or more, that might be more of an issue, but a week isn't very long.
