How so? It seems consumer hardware & software (phones, bluetooth speakers) work much better than expensive, name brand cars. I think this extends to aerospace and medical equipment, the manufactures of these devices know their industry and their engineering but are 5-10 years behind in the implementation and polish of basic things like bluetooth. Medical devices especially are notorious for poor security; unsecured endpoints, outdated/unsupported OS versions (think MRI machine with 20 year lifespan running Windows XP Embededed).
