> Yeah, I completely agree. Vehicle manufacturers can't just come and change out the steering wheel and dashboard in your vehicle, for example.

Actually, they can. There was a huge airbag recall a few years ago, affecting maybe half a dozen automobile manufacturers because they all bought their airbags from the same supplier. In at least one case, the dash had to be modified in order to fit a replacement airbag because drop-in replacements could not be procured quickly without disrupting new car production. It would not surprise me if some of the cases also required modifying or replacing the steering wheel.
