You and I survived, but quite a lot of people didn't. The aim of the various driver assistance devices is to increase the number of people surviving in the future.
I have an aviation background and when aircraft automation first came in, the old and bold pilots resented it. Especially in an emergency situation, they wanted to be the big important hero guy manhandling the flight controls. They resented some computer doing it for them. But history has shown that they crashed quite a lot, whereas after the introduction and acceptance of aircraft automation, accident rates were substantially reduced. Of course competent use of the automation requires training, and that is probably where the problem arises with automation in cars - there is no training on how to monitor the automation, or even how it works or more importanly how it behaves.
For example I suspect a lot of people don't realise that whilst if you have ACC engaged and the car in front slow down, your car will brake as necessary (up to a maximum braking limit), whereas if you come round a corner and encounter stationary cars ahead, it won't brake and will plough straight into them. This is the sort of thing that ought at the very least to be highlighted in the manuals - but even then, lots of people don't read the manuals! So really, there should be mandatory training on how a car's driver-assistance systems behave, just as there is for aircraft. Never going to happen, I know!
