Kirk, we have a large public high school parking lot iway out in the country that I take the car to occasionally on a Saturday afternoon. You can do a few runs around an impromptu skidpad followed by a few hard brake applications - or I do. I've never had anyone bother me, although I am sure it is illegal in some regard. I suspect if the police did come out, the first time at least they would simply ask me to stop, and I would.

You might try that just to make sure the car runs, stops and turns.
