The problem is the justice system assumes 1 person kills 1 other person.
In reality there were 100s of people in the chain of events, from the safety driver being bored and watching their phone, to the person who hired them and didn't train them properly, to the person who invented the safety driver system and didn't think people would get bored.
Then you have the people who made the decision to turn off some of the subsystems of the car and then test it at night with no extra precautions, and every programmer who let that happen.
The the management of the company who provided the wrong incentives to their employees.
And that's before you get to the people who designed the roads, and the lack of social care to look after people who for some reason are homeless
