Citation needed, certainly for the case at hand, where you’re suddenly required to drive a car in an emergency situation.

(Edited to add the claim I responded to, because it looks like a few replies didn’t look at that context)

On the contrary, I’d challenge anyone to find a non-contrived example of a crash that is unavoidable with 10 seconds of warning. Driving off a 1600 foot cliff does not count.

Your car has gone the wrong way down an express lane some distance, and deactivated when a semi trailer traveling 75mph in the opposite direction is detected. There is no shoulder, and it's stopping distance plus yours is greater than the remaining distance between you (.1 mile is way insufficient)

”Wrong way down an express lane” is super contrived. Those are the kinds of clear cut issues that self driving is guaranteed to be better at than humans.

If semi can stop in 6 seconds sounding horn would do it.

Every crash is avoidable by definition.

Human error/poor decisions, mechanical/electronic failures, acts of god could all reasonably be labelled as reasons.

Regardless of time.

Not every crash is physically avoidable _given a time constraint_. When you're a millisecond from impact, there's nothing you can do. One second, there exist many cases where there's nothing you can do.

10 seconds before impending collision, and it's hard to imagine the case where there's no time to react in some way that avoids the accident.

You are always required to drive the car. Autopilot does not replace an attentive human driver, there is no excuse for being distracted or spacing out.

Pretty sure you could not, and your confidence is terrifying.

Set a timer and watch it count to 10s. It’s a long time.

Remember, people fall asleep while driving cars pretty regularly. I know people who have fallen asleep driving on the freeway, woken up in the median, and just guided the car back on the road to continue.

Are they stupid for not taking breaks, etc? Yeah. But is it unreasonable to think 10s for taking over control from sleep is doable? No, it’s doable for people with the right mental state. The most common mistake is overcorrection on waking up.
