Because if your family member is violently killed by a robot car doing something that seems inexplicable to the human mind, and with a fact pattern that doesn't match up with normal human error accidents you're used to, you're not likely to be consoled with a reminder that four people you've never met supposedly are still alive because they weren't killed in some place you've never been by a human driver that never took the wheel.
