If your premise is "robotaxis are so much better than human drivers" then this is almost a disaster. This is only the 10th city they've deployed to, all in the south, and nowhere there's significantly inclement weather. It does not bode well for their expansion plans.
Better is an arbitrary statement. By number of jobs robots lose, by number of sexual assaults by taxi drivers they win. Pick the wights for very factors and you can select anything as the best in category.
Safer, cheaper, etc are less arbitrary.
I'm not sure why you would say there's no significant inclement weather in Atlanta. The flooding this week was not super common, but also not unheard of. It rains here a LOT in the summer
It's a delay. The question is how long? Doesn't seem unfixable.
Human drivers are very very bad. Being better than humans is a low bar with plenty of room to be bad as well.

You may be relieved to hear Waymo is rolling out to Portland, Oregon. It's not in the south, and with over 150 rainy days per year, it ranks among the rainiest US cities.
