The car has become an appliance for the majority of people. It is, without a doubt, the most cost-effective and user-friendly appliance on the market today. The tech industry tends to describe its products as "user friendly." If the car had the same user-friendliness as a PC, it would come in six or eight wide boxes, with the owner having to mount the engine, wheels, and seats, as well as load the programmes into the various electronic devices, and the paperwork would be unreadable.Besides which, it will break down every 100 miles or so in general. This metaphor is supposed to be funny, but it does reflect the relative high performance of modern automobiles' various new subsystems. Although its stated function is transportation, modern vehicle electronics should provide it with a wide variety of auxiliary capabilities, as this book would indicate.
