Possibly, thanks to assholes as depicted in that video (which may be fictional). Apple does not want the liability or reputational damage from enabling someone driving a car and getting into a wreck, even if that prevents some other uses.

FYI - I don’t know what the rules are that they put into place and what I read was based on comments from some early demos that Apple was giving so it remains to be seen what you actually can and cannot do while wearing one. I’m sure that this will start to come out now that people are using these in the field.
