Car Watching

What to do if your car cannot leave when the exit is blocked by another car, and there is no smartphone number under the windshield?
Or when tow trucks are trying to steal someone else's car, and you want to prevent it?
Or maybe you would like to buy a car and are looking for a way to inform its owner about your desire?
