One undocumented feature of my car is the taillights being on the same circuit as the dash backlight. This is so when the taillights blow the fuse, your dash goes out, and you think to check the fuse for the dash, and that also fixes the fuse for your taillights. I did not know this, and on occasion I would just drive without the dash backlight. Until a kind motorists yelled at me in Australian and I figured it out. There is a lot about cars that parallels programming, especially if you work on your own cars.
