Earlier quoted context omitted.
Waymo is safer than a human driver already. https://www.nbcbayarea.com/investigations/googles-waymo-safe... Of course there will be locations where humans are required, but we can already start using computers in those locations where they perform better.
Where I drive daily I constantly have to make decisions which no self-driving car system I know about can possibly do. They don't foresee upcoming gridlocks caused by you driving completely legally but blocking (again, legally) a car from crossing to a side road, that car again blocks the car behind it, which blocks the car in front of you from doing a left turn, which means that you can't move and unlock the gridloc…
So again, while I think ultimately the automated systems should also do what you're talking about, right now, if the other article is true in its claims that Waymo is safer, it seems sufficient to follow the rules to achieve a certain level of safety.
