Eh, in the US you don't even need a company nor a lawyer, a car is enough.
See https://www.reddit.com/r/TrueReddit/comments/1q9xx1/is_it_ok... or similar discussions: basically, when you run over someone in a car, statistically they will call it an accident and you get away scot-free.
In any case, you are right that often people in cars or companies get away with things that seem morally wrong. But not always.
A bit over five years ago, someone struck and killed my friend in a crosswalk. He was a fellow PhD student. It was on a road with a 30mph limit but where people regularly speed to 50+mph.
He was an international student from Vietnam. His family woke up one day, got a phone call, and learned he was killed. I guess there was nobody to press charges.
She never faced any accountability for the 'accident'. She gets to live her life, and she now runs a puppetry education for children. Her name even seems to have been scrubbed from most of the articles about her killing my friend.
So, I think about this regularly.
I was a cyclist at the time so I was aware of how common this injustice was, but that was the first time it hit so close to home. I moved into a large city and every cyclist I've met here (every!) has been hit by a car, and the car driver effectively got only a slap on the wrist. It's just so common.
