Roadkill, i disagree with both your point as well as your tone. OP is not stating he wants the car to take responsibility. But that he's disappointed it didn't appear to help avoid an accident. I can picture you 70 years ago mocking folks for wearing seatbelts when they wouldn't have to if they just "used their brains"...
Think of these features like a second seatbelt and keep the dialog constructive...
The problem is not at all like your portraying it. The seatbelt is there to help minimize the effect of an accident, just like airbags. But they are not there to eliminate any injury if you get into one.
My comment is more directed to the way that these safety features are being promoted and the expectation being taken by the public (or more to point the owners of these vehicles). The auto-breaking and lane departure, along with blind spot detection or any number of features are just tools to help the driver minimize the chance or effect of an accident, not to eliminate.
There is an advert that is run here I see all the time for Hyundai, where there is a kid getting his first bike and the parents give him a red ribbon to put on the handlebars saying it will help him ride faster. It shows him riding races and going really fast. At the end, if shows a small kid about to open the back door on the driver's side and it doesn't open and you see the cyclist ride by.
a) Unless you watch carefully you would miss that the cyclist is following closely behind a car that actually activates the door lock system as a bicycle by itself would not.
b) The system wouldn't react if a car changed lanes beside the parked car rather than coming up behind, nor if the car is a bit further back so you would be in the middle.of swinging the door open as the car will be passing, so the lock system itself is not infallible in all situations.
c) Show the totally wrong message that you need to check your blind spots when opening doors as it is your responsibility not the cars.
I was not commenting or being pissy towards the OP. Just more grumpy old fart towards the general direction or attitude that seems to be growing within the population. Perhaps it is just that media just shows us the idiots who simply want to pass blame onto everyone else for the stuff they did wrong.
