Such detailed database of fine grained road geometry gets stale very quickly, due to road maintenance and road construction. In US highway lanes are shifted sideways frequently.

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.

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.

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

For common routes, yes. For getting to John's house, where the path there sometimes floods, no.

		So the first waymo to get to this less used road to john’s will not have the data rather than every waymo that travels down a new highway, that then becomes a problem if it rains. One car with an issue of first coincides with rain on a less used road?
