Well It was suppose to STOP
I have been working with high tech, safety critical gear almost all my adult life, work within aviation, have a pilot license, fly planes with auto pilot never hesitate to engage the AP if appropriate, and learned one thing during my 40 years of work experience... human fail more often than machines...
As for my car, I trust it today, while initially when I bought the car I was a bit skeptical also, and I still have just a light control setting for the Y axis (left/right movements) lane keeping function. "Light" means it will pull the steering wheel lightly back and gives me an optical information with a picture in case it believes I am mistakenly changing lane or about to drive off the road, similar to the stick shaker in a plane. There is no doubt in my mind that the car stops if the truck in front of me suddenly stops, the likelihood of me missing the truck or keeping too close distance to stop is much higher than failure of the feature without previous warning. Of course, there are settings for the distance keeping function, which is adapted to the speed and you can't really set distances below any reasonable distance. I also get warnings when some or all the sensors are faulty (never happened), or dirty (happens now and then), and some or all the safety features are disengaged when that happens, like for example a misty winter morning with frost or road dirt/mud end up on the sensors.
Of course, I would not like to sleep when I am driving, but I actually have a work mate who fainted while driving on a highway with traffic and normal highway speed (110kmh in Sweden). His car stopped after a normal deceleration at the side of the road on it's own, when he woke up he realized what happened. His wife actually wrote a letter to Tesla and expressed her gratitude, the feelings she had since he (and maybe others) actually survived because of the built in safety function of the car.
But this is a CNC forum, so this was just a small OT about safety and automation. Automation works and is definitely more trust able, making less mistakes than human.
