Keeping the safety drivers in the beginning, scaling up, and getting a year or more worth of actual real world use, before slowly scaling back the drivers is what I'd call a very responsible choice. IMHO, to do less would be reckless showboating that could do unimaginable damage to the AV industry, as well as end up endangering lives. In the tech industry, we don't like to wait, we like moving fast, taking risks, shi…
I'm sorry but where does this "one year" expectation come from? What says that Waymo needs a year (or two years, or ten, or three months, etc) to start "scaling back the drivers"?
From what I can tell, the only way to judge the competence of their driverless systems is to compare where they are today with were they were 10 years ago when they started out. However, this is next to impossible- that data is not public.
So, where does that "one year" optimism come from? Autonomous driving won't magickally become easier in a year from now.
