The big picture looks different when you're buying and driving the car versus when you're a stockholder who doesn't own one.
For example, I have a loaner which is a new car. I have absolutely no idea if I have AEB. When I ordered my own car, I was told it had AEB. But it didn't for 6 months of ownership. That I didn't get in an accident that killed my family matters to me because I'm alive. That I didn't get in an accident that killed my family matters to you because TSLA.
“Automatic Emergency Braking, a new collision Avoidance Assist feature, is designed to automatically engage the brakes to reduce the impact of an unavoidable frontal collision with another vehicle. The brakes disengage when you press hard on the accelerator pedal, release the brake pedal, or sharply turn the steering wheel.”
It doesn't claim to prevent a crash it just claims to reduce the intensity. I don't think AEB has saved anyone's life, it's only reduced injuries. I'm not sure why you think it's a life or death feature.
Look at actual deaths in a Tesla. We have:
* falling off the side of a cliff
* slamming into a concrete wall at high speed
* running under a semi trailer at high speed without trying to brake or turn
* rear ending a street sweeper at high speed without trying to brake or turn
maybe I missed one or two but all of these happened before the current 2.5 HW came out. None of them were prevented by AEB.
It takes an accident of a very specific type and intensity for AEB to make the life or death difference. To fast/hard and nothing will save you, too slow and you'd survive without AEB, the Goldilocks accident is a very small window for this equation.
I don't think we will see new deaths that could have been prevented by AEB in the few weeks a small portion of the fleet is waiting for 2.5 HW to enable AEB.
