I know today's cars are a lot more standardized.
Check out the dash on this Citroen DS - notice most controls are unmarked (or, the ones that are marked are using French):

Then, when it came here, it was Federalized, disabling or changing some controls.
Left turn signal: push downward; knob springs back to middle.
Cancelling the turn signal: pull it towards driver. Or, push upward just enough to stop it blinking left but not enough to start it blinking right.
Try to figure out how to turn the interior heater fan on. That knob actually pulls out. Everything else that's the size of interior heater fan knob is something that rotates, not pulls out. It's too small to be a pull-out knob. So, you freeze, and can't see out the front windshield, until you figure that one out.
At least the cigarette lighter was easy to figure out.
Two knobs to the right of the manual choke.
One knob right was the manual windshield washer pump. Pump too hard and you blew the rubber hose off the back of the pump, getting the compartment wet and necessitating a reacharound by your thin-armed kid (me) to reattach.
I think Doug DeMuro would have a coronary reviewing one.
