I've seen 20+ car crashes outside my window in the last few years and cars usually either stay right where they stopped until police (and later tow trucks) arrive in the case of serious accidents or else pull over to the side of the road to exchange insurance information in minor accidents. In some of the moderate cases, I've seen the drivers try to move their cars out of the way of traffic but they still stay at the scene. I've never seen a car pull into a parking lot after an accident despite there being one literally right there where I live.
