This is the perfect expression of chronic windshield brain. If you are driving anywhere near the limits of dynamic stability on a public road, then you are already driving dangerously. Also, computerized stability control works better than 99.99% of human drivers.
The limits of dynamic stability go down drastically when the brakes are locked up. You can be _far_ from the limits of dynamic stability when going around a bend in the road, but if your car locks up the brakes mid-bend, you can unexpectedly go from nowhere close to those limits to exceeding them in the blink of an eye. A human driver would wait until they've straightened out to brake hard, but the computer in a car is entirely at the mercy of whoever programmed it. Hopefully it would do the same, but do you really trust Tesla (or whomever) with their move-fast-and-break-things additude?
Then there's the fact that automatic emergency braking requires the software algorithm to make decisions based on data that is a lot more complex and ambiguous than the data used by electronic stability control and ABS systems. It's much easier to detect steering angle and wheel slippage than it is to detect how an object in the distance is likely to behave.
Confirmed: you don't understand this subject. Any readers who find themselves needing to stop a modern car in an emergency are advised to stand on the brake pedal with maximum force while the computer sorts the situation out.
i don't think you fully understand how many edge cases there really are, and the full range of conditions people here expect autonomous cars or even driver assist systems to function in.
As a very simple example, i sat my driving test in the Netherlands. Literally the first thing my driving instructor taught me was that tires have finite grip and that changing speed or direction requires grip. Doing both at the same time, as you do while driving along a curved highway off ramp can be very dangerous in slippery conditions.
Many, many times, the auto braking and lane centering system in my hyundai car has caused the car to skid in light snow. i have lost count of how many times this has happened. With my previous "non smart" car, this never happened because i know how to drive in the winter.
Respectfully, not all driving conditions and styles are dangerous.
