If you've lost traction and are skidding on ice, the traditional step one is to shift into neutral (or clutch), before steering into the skid and then attempting to recover traction. I've actually used this, but only once.

That technique works, but stability control has made it largely obsolete. I used to do that with the DS-21 all the time because the Michelin XAS tires weren't the best snow tires--even though you got a snow tire certificate (once proper 180R15 snow tires came out, it wasn't necessary). I wouldn't ever expect to need to do it in a Model S.
Stability control isn't perfect; on rare occasion I've had both ABS and stability control fail to trigger in low speed / extremely slippery conditions. I assume all four wheels locked so fast that the car thought I was stopped. So conventional techniques still have some merit.

Interesting Observation with Parking Brake
I maybe delusional but I have observed this behavior 3 times now in my Model S. When I am reversing into my parking space and get between 1 and 1.5 feet of the stairs to my home with the foot off the accelerator and creep turned off, it pops itself into Park. It was strange the first two times, I thought I hit something. The third time however, I watched it carefully and it did it again, popped into Park within 2 feet of the steps to my home, as if it could sense it. Again, it was coasting very slowly and with my foot off of the accelerator. I must strongly caution you however if you should try it in your Model S. I'll see if I can get the behavior on video.

Good question! I am looking back out of the rear window at the time and it could very well be that I am lifting my butt up higher to get a better look. Very good point and something I will be paying more attention too!!

I must be consistently lifting my butt up at that same point each time. Will try and try again, I park in the same spot so it's inevitable anyway!!

I couldn't imagine that I was the first to discover this, although it would be beneficial to me! If I have to lift my butt up to see how close I'm getting, maybe the car should pop itself into Park letting me know, "that's close enough thanks!"
