if you are at home, you take it in, at work, if you are going to be stationery for many hrs, you can lock the steering wheel in the back of the vehicle, remember they want a quick getaway, not fumbling around for any length of time, i dont know for sure, but i think they can be used with steering wheels with air bags,
or you can do what mr bean did
