You definitely will run into legal issues depending on the state. Some states like California you can only get a DUI if there’s evidence you moved your car, but in other states it’s a lot less clear - and you can be charged with any appearance of intent to drive, like sleeping in the driver’s seat. Not to mention the possibility of getting a trespassing charge in a private lot overnight.
