This is still a variation of the trolley problem and is plagued by a human sense of morals and ethics making the question unanswerable.
Humans still exist due to an instinctual drive for preservation of "self" so keep that in mind. when interpreting the results of that study.
You said you don't feel that was because you're the driver. So let's look from perspective of the car.
If the car is tasked to avoid objects on the road will it swerve to avoid a squirrel throwing you into a tree?
We might agree ok, hit the squirrel.
What if it was a baby in the road and the driver was a 97yr old man?
You might say throw the man into the tree, but remember you're the car and it's not your job to make such decisions. The 97 yr old man was carrying three car seats with 3 babies in the backseat. If you didn't hit the baby in the road you just killed 3 in the back.
You can come up with millions of scenarios but at the end of the day the car should do whatever it can to protect the occupants AND avoid such dangerous situations in the first place thus helping everybody.
As for deer and AP2. When the
moose thing was announced that was refering to AP1 and using radar only for detection. There's no reason in AP2 they couldn't use the cameras for animal detection of any size. Image recognition is quite good nowadays.
