More real Linux experience: Your car doesn't have a switch for the turn signals, instead it has a bunch of unlabeled wires under the hood to activate them. When asking around online, people complain about you not knowing it outright, and not hooking up an automated switch to it.
Even more real linux experience: The turn signal is well documented, labeled really obviously, and anyone will point you in the proper direction, but when you use them the brakes stop working because of an undocumented bug in a proprietary windshield wiper driver, and only you seem to have this problem.
In the end people just complain that it's too complicated and just don't use the turn signals (seriously there's actually dumbasses who regularly or semi-regularly don't use their turn signals in real life).
