Have you thoroughly lubricated those gears in your head? Are you firing on all cylinders? Is your ECU updated and running optimally? Hopefully so, because you'll need all your automotive knowledge for this test.
Cars are complex machines, so understanding them takes a lot of knowledge and experience. People spend their entire lives learning how cars run, how to fix them, and working on improving designs. As a result, just because you learn about how cars work once doesn't mean your knowledge will stay current. Automakers and aftermarket manufacturers are constantly working to improve how vehicles of all kinds work.
Then there's the culture that's been built up around cars. From racing to shows, clubs to car chases in movies, car culture is everywhere. It's very much affected by society and what it values, plus the evolving design and capabilities of cars. You have to be an amateur historian, sociologist, and anthropologist to have a command of this knowledge.
The business end of the car industry is another area you should understand. It can include how automakers run, mergers, and more. This is a lot of ground to cover, and the only way to test your knowledge is to take this quiz right now!
