You really need to drill down more than a paragraph about a case like this to make any sense of it. If the auto maker build a vehicle that did not met the crash test standards for that year the vehicle was made. Then the auto maker should owe every dollar. But it could be it met that standard and that standard was not good enough. Then who should be blamed the feds or the auto maker. Well the auto maker is always the big easy target. No matter who makes a auto, people will die in them. It's to bad, but it's a reality. They should be as safe as possible under normal means of use.
Followed up with before the money if it's paid out, Ford will place as much blame on the driver as possible. And they should if facts like the tire that blew was under inflated, to old to be considered safe, wrong size etc. Driver was driving to fast, not using seat belt etc etc.
