But are they not continuously updating the road database with their fleet?

Pretty sure they already rely on such a database for positioning, so they already have that problem.
But yes, this wouldn't work for other self-driving systems that don't rely on HD maps.
I traveled to Austin 3 weeks ago and there were entire highways not on Google Maps.
Apparently they were built in just a few months.
