They're consistent on this.
Tesla tells them nothing. I loved the story about them coming to work on a Friday, finding the Model Ys sitting in the showroom and being told that it's just gone on sale. Zero heads up for the workers on the front line, it's the silicon valley way.
Thats exactly what our local showroom (Miranda) said. First thing the staff new about it was when they walked in at 8am and saw it in the showroom.
