My wife and I independently took the new Model 3 to the Car Wash without knowing that the method for shifting into Neutral has changed from the Model S.
I pulled up and drove into the lanes, and then couldn't figure out how to get into Neutral. I completely clogged up the car wash lane and they had to move cars out of the way so I could back up.
As I left, I searched for how to switch into Neutral and found the answer on this forum. Like I said, the same thing happened to my wife, so I'm guessing it may happen to many new Model 3 owners.
On the S, you push all the way down (basically, 2 clicks) to get into drive, and then softly push it back up one click to go into Neutral. That does not work on the Model 3!
On the 3, you push down (1 full click) to get into drive, and then softly raise the stick WITHOUT clicking for a few seconds and it will shift into Neutral.
I hope this helps somebody. I felt very foolish not knowing how to shift my car into Neutral!
Actually, I've noticed that the up (with no click) on the 3 goes to neutral immediately. You need to hold for a second or so in order for it to stay there.
