I won't comment on the pick up / drop off situation, but another important scenario is right turns. In California, drivers are legally required to merge into the bike lane when making a right turn. This is for the safety of the bicyclists, to avoid the dreaded "right hook" collision.
Dylan Taylor, a beloved Menlo-Atherton High School football coach, was killed last year in one of these collisions:

(Scroll down to the comment by "T R" which describes better than the article itself what likely happened.)
Unfortunately, I've almost never seen a driver follow this law. Everyone studiously avoids the bike lane and then cuts across it.
The bike lane marker changes from a solid white stripe to a dashed line as you approach an intersection. This is supposed to be a hint to merge into the bike lane. It isn't working.
I post a reminder on Nextdoor once or twice a year about this. I'm taking the opportunity to also post it here for my California neighbors.
It would be interesting to see if the Waymo Driver follows this law. My bet is that it does.
The San Francisco Bike Coalition has an excellent page on this topic:
In the nearest fairly large city, there's a (sometimes separated) bike lane, a bus lane, traffic lane, and turning lane which all intersect to various degrees. It's all clear as mud especially after dark when both bicycles and pedestrians are frequently darting into traffic from behind cars without lights. I'm just surprised there aren't more accidents.
And when you do that, (most) cyclists behind you get angry. (Most) cyclists are rude and act like they own the road.
I don’t live there, but for what it’s worth, this seems to be followed fairly consistently in the San Diego area whenever I’ve visited.
huh i didn't know about a specific bike lane law. but i do know the law that right turns must be taken as "close as practicable" to the right side of the roadway. plus there's the hint of the dashed line. Sneaking into the extra space to the right isn't a shortcut -- it's required by law, ie even without a bike lane.
in california, which is where the incident in TFA occurred.
As soon as I saw that headline I knew it had to be on Middlefield... lo and behold. I've been aalmost hit there twice and actually hit there once. once with a car taking a left. another with a car taking a right
