Other than people complaining that they don't like that they have to slip constantly to get the front motor to engage? They want it in a 50/50 split for driving in slippery conditions for better control/driving feel. This accomplishes that automatically, which is how Elon likes things.The sensors are constantly adjusting power distribution in real time depending on the changing levels of slip ... whether caused by a snowy surface or anything else. There's no reason for there to be a defined mode.
You mean other than he literally shows that once you gun it and trigger a slip it stays in a ~50% split mode for a long time afterwards even if there is no further slipping? It seems like putting it in park resets it back to standard, I don't know that he identified how long it actually stayed in "snow mode".The software may well have been refined to better deal with slippery surfaces but I don't think it's like a switch where you are either in "snow mode" or "normal mode". There's nothing in this video that makes me think it works in that way.
