The justice system is entirely our own creation and we have arbitrarily decided who and what is to blame when driving causes the significant amount of violence that it causes every day. If we didn’t place the blame on the XYZ for XYZ reasons, or if we didn’t have no-fault accidents, then driving would be functionally and practically illegal. So we make up methods of keeping it legal to the level that we’ve deemed necessary or desirable. Does it matter whether a person chops up another person vs a car decapitates another person? Functionally no. The person is still dead, their family is still grieving, and their contributions to their community are still gone. But we’ve decided that one of those is a crime while the other is an “accident.” Coincidentally, a group of highly influential and rich car manufacturers have also lobbied trillions of dollars to “encourage” that decision.
