This is exactly the question I was asking, thanks for your input. I know the highlighted examples of 'bad behaviour' in waymo's are somewhat sensationalized, but its hard to quantify how that translates to impacting other users of the environment. I agree humans are very prone to this sort of bad driving, which was what made me ask the question about waymo to begin with. Specifically things like lane keeping, impacts on cyclists pedestrians etc... things you mention.
Although my brain can't help but see waymo's more as "Meatwagons" than human driven cars, I get your point :)
It would be curious to see relative levels of driver assist and its impacts on things like that outside of crash and injury statistics from crashes, but it would be very hard to measure and quantify.
