Since the automobile first came about at the end of the 19th century, maintenance and repairs have been an essential, albeit annoying, aspect of car ownership. Every single vehicle that's ever graced the world's roads has needed some sort of repair throughout its lifespan. During the car's early years, owners took the responsibility of repair into their own hands, and most vehicles even came with their own basic repair instructions in the owners' manual. However, with the rise of digital tech, this has changed dramatically, and now, even top sellers like the Toyota RAV4 and Tesla Model Y are veritable computers on wheels.
