YSK If you were ever in a car accident in a parking lot, or anywhere on private property. Sometimes the police will not come out to the scene because it’s on “private property”. You have a legal right to request that they come to the scene and at least take statements from all the parties involved.

YSK 如果你曾经在停车场，或在私人财产的任何地方发生过车祸。有时警察不会到现场来，因为这是在 "私人财产 "上。你有法律权利要求他们到现场，至少要向所有相关方录取证词。
