We say “unusual” not because they're analog and not based on a display screen like the big hunk of LCD in the middle of the dashboard, but because they are extremely familiar.
The reason for their familiarity is because they don't look similar but are actually identical to ones found in a Mercedes-Benz E-Class W212 pre-facelift.
The transmission gear lever on the steering column and the windows switches are taken straight from the Mercedes-Benz, and they're the only ones we found visible, because we have a feeling that the sticks with which you control the turn signals and the cruise control system are also borrowed from the E-Class.
Considering the rather close relationship between Tesla Motors and Daimler AG we aren't very surprised, but we're also wondering if there are other Mercedes-branded parts in the Tesla Model S also.
The cup holders you can see in one of the two Model S photos can also be found in the Mercedes-Benz M-Class W164, for example.
