Is the TL;DR of the article that they're launching this (https://waymo.com/blog/2021/12/expanding-our-waymo-one-fleet...) new vehicle design?
I read the whole thing, but, idk, surprised they didn't include a picture or clarify if this is strictly hardware, or hardware + software changes (with the software changes maybe back propagating to existing Drivers)
Ultimately there will have to be some sort of new models regardless, given the vast majority of the fleet is Jaguar I-Paces, a car which ended production with no successor in 2024. Waymo bought the final 2000 cars to come off the line.
