That was my first thought when I read this. I wonder how much they cost and how heavy they are. There may be a market for a half size (driver side only) or smaller version for this purpose. The club is a joke as they quickly cut the steering wheel. Using a boot ( a guy near us does this) is a bend over PITA to me. Slapping this on the windshield seems much easier???
Years ago I had an idea for an anti-theft patent where the drivers seat had a setting that moved it forward to a maximum point and bent it over so it touched the steering wheel blocking access to the steering wheel, controls and maybe ignition/push button start.
