Well technology doesn't scare me as it does some. I would not buy a modern vehicle without all these safety items.
They aren't there to take away responsibility (and they cannot) or because owners are stupid, they're there because they can and do react faster than the operator and never take their eye's off the road like humans do.
I used to work on similar systems for aircraft. You'll notice they don't crash nearly as often as they did a couple of decades ago. It used to be that the main cause of aircraft crashes was pilots flying perfectly healthy planes into the ground (known as CFIT) - just like people crash perfectly healthy vehicles. Because of modern systems like new cars have, that is no longer the case.
