There’s clearly contradictory information going on, so I can see why a customer may be confused.
If I take the perspective of someone who isn't informed about the technology, I can see how they could think that the technology is safe and Tesla is putting excessive warnings because their lawyers want them to. I think superfluous warnings on so many products has trained people to take warnings less seriously.
Tesla needs to get their story straight. They're trying to talk out of both sides out of their mouth, and using whichever statement is convenient at different places.
My understanding is the video is a demo of what their research technology can do as a one off demo, not recommended procedure.
