Good tip on towing a vehicle I learned from someone many years ago: wrap a piece of white tape or tie a bright ribbon around the top of the steering wheel. If your camera is halfway decent you can see the tape, allows you to back up a short distance if needed, you can tell when your steering wheel turns and then stop before you do any damage. From experience I can tell you you won't get very far.
