Re: country & western singers
My guess would be that an autonomous car gets out of control of it's AI by the latter overloaded with conflicting information and rules so that in order to ditch the lot it needs an emergency routine to follow.
Isn't that how humans work? If our cerebral cortex can't handle a tense situation, the decision-making responsibility is handed over to the amygdala, which has a small bank of emergency responses (fight-flight-freeze). The available responses aren't always appropriate, but they're usually better than mulling it over until it's too late.
If it's worked for animals over a billion years of evolution, it seems a good starting point for devices we design today.
