Sports themed steering wheel locks such as the famous "Club" product. All sports are patented, the patents available here are for hockey, golf, baseball, and cricket.
I have already spoken with Major League Baseball and they are open to providing licensing for this product. However, the company needs to be in business for about a year before they are willing.
It's a great new marketing idea on an existing product that is successful.
The only thing I can add here is that I already have a manufacturer in China lined up that can produce for around $15/unit landed to any Western port.
