This isn't about Tesla.
It's about the trolley problem.
From 2017 and still an issue...
The trolley problem is solved with some simple rules.
Minimise casualties outside the lane of travel in all cases.
Objects or people in the lane of travel are to be avoided via lane change or leaving the lane for a shoulder if possible , emergency braking if possible. Leaving the shoulder and lane only if clear of people and other obstacles and the vehicle is not in danger of roll other or impact due to loss of control on a loose surface. The impact is always in the lane of travel of the above options are not viable with maximum effort braking up till impact. Persons or objects entering the lane of travel trigger the above logic and get hit it they are the least worst option for the vehicle occupants since an intrusion into a lane is on the intruder not the vehicle who has the right of way. This applies for cross traffic at intersections running lights or stop signs their lawless behavior voids their impact avoidance hierarchy standing to the very bottom.
It’s cold hard logic and puts the casualty on the party who is not where they are supposed to be. The law will see it this way as well.
Having worked in insurance there is no such thing as an accident there are incidents and some party is always at fault for the failure chain. Always without fail. A error was made purposefully or via neglect or inattention but without fail an error was made by one or more parties leading to the failure chain and the incident.
