Unpredictable drivers aren’t a challenge compared to weather. They’re just 3D objects to avoid. That’s a solved problem.

The thing about weather is that with a fully automated fleet they can just stop and give up on driving instantly. Rain in Miami doesn’t tend to last very long except in specific storms like hurricanes. Waymo can just not operate during those times.

I’m very doubtful that a lot of these inherent problems with the technology are being rapidly solved. See: the article.
