If you made an industrial robot and sent it out in the street and it killed someone holy shit you would be in trouble.
But with this one trick you can evade all responsibility and criminal liability:
Just make your killer robot look like a car.
Oh. and be sure to put a human in it so they can take the blame if you kill someone, it's called a "morality crumple zone". It doesn't matter who, they're just a sacrificial lamb anyway.
Bloddy hell.
