Any modern car is going to have an enormous amount of robotic assembly involved. Having humans can give you more flexibility (robots take time to set up), but expose you to more quality problems because they're inconsistent. But many things just can't be done that well by humans.
That might be the case now, but who's to say that won't change in the future? What will happen when robotics and computer vision advances to a point where employing a human on an assembly line doesn't make economic sense?
