BTW. I saw those slipstream wheels.
Also I LOVE THE STALKS! Thanks Elon!
Having R-N-D-A on one monostable (returns to home) stalk is the best way it could be done. Push up for Reverse. Push down for Drive. Push down twice (or push down hard or push and hold) for A (Autopilot), push button for Park. Also push left button for swipe and push hard (or push and hold) for wash. Most likely Push and hold P for emergency brake.
Actually, these stalks are similar to Model S and X - i.e. they are sourced from Mercedes.
