This is a solved problem. Many people I know including myself use Waymo’s on a weekly basis. They are rock solid. Waymo has pretty unequivocally solved the problem. There is no wait and see.
I mean if waymo had unequivocally solved the problem the country would be covered in them, and the only limit to their expansion would be how many cars they can produce. Currently they're limited by how quickly they can train on new areas, which is likely slowed by the fact they're using over 20 sensors across four different types. On the other hand, Tesla could spread across the country tomorrow if they were reliable enough. I would think solving autonomous driving would imply you could go nation wide with your product
Right, nobody has solved it. If either company had solved self driving, it would be in basically every US city. While it is my opinion that Waymo is further ahead, no company has solved the problem yet and because of that it's still not clear what the best solution will be.
