Steering wheel and pedals, sure. Gearstick, mostly, although the positioning of reverse is different in different cars, and often there's a little trick to engaging it (push the stick down, or pull up a ring just under the handle). The shifter on automatics is often weird (but at least you never have to use it while driving).

Headlights, wipers, cruise control, trip indicator, window controls, A/C, radio -- all different on different cars.

Even the turn signals can vary. If I'm signalling left and want to turn it off, I expect to be able to cancel the signal by clicking the lever upwards, but I've driven cars where that causes it to signal right instead.
