I think because Tesla's marketing is hyperbolic so that they don't sound like other car manufacturers. They've made automation a large part of Tesla's future offering and have not been able to deliver but strong naming makes it looks like they will soon. "Advanced driver assistance system" simply does not sound as sexy or impressive enough for the shareholders. There are other companies with hands-off, eyes-on systems that don't make it a centerpiece of their offering but are steadily overtaking Tesla in quality, range, volume & capabilities. Maybe we need some legal definitions so that marketing speak doesn't cloud the awareness of drivers of what their car is really capable of.
