Unfortunately, the Club is really quite
ineffective as anything other than a
visible deterrent.
A car's steering wheel is made of lightweight metal so that it bends with a body in case of impact in an accident. This makes it very easy to cut through with either a hacksaw or bolt cutters.
Make a single cut in the steering wheel, slip the Club off the wheel, start the car and go... The whole process takes about 60 seconds longer with The Club than it does without it. That's not enough for me.
