You say this flippantly, but I think this is actually another very good example!

We even do it for obviously unintelligent inanimate objects. A rollercoaster ran too fast for its tracks, killing 10 people. In that sentence, the roller coaster is the subject which took an action and caused death — obviously the roller coaster is not ethically at fault here, the people who built the rollercoaster are at fault through negligence.

Although this example and the ones around cars both demonstrate how we tolerate some degree of "accidents" from humans as no-fault, which is fair. I wonder how that fits into this analogy? I suppose its all about intent (mens rea) and judgement: did they intend for the roller coaster to harm people, and should they have reasonably predicted that the accident was likely to happen.
