They don't seem to actually working toward L4 any time soon. It's just a steady drip of little features like "stops at stoplight" that are progress to fans, since none of the other self-driving companies are releasing anything, but what Waymo/Cruise/Zoox are stuck on (and have been working on for many many years) are much more nuanced problems that Tesla still have to face some day.
