In case you ever wondered whether you can shift into neutral with impunity while driving at freeway speed, you can and it will result in an urgent message to stop doing it. I accidentally hit the neutral button while driving and the car shifted to neutral as it would if stopped. I got a warning message that said something like "Take your foot off the accelerator and [something something]". I was a bit panicked, so I didn't decipher the entire message. I pulled over and stopped to shift back to drive, no harm done.
