Maybe I am too cynical, but am not sure that all these "assist" functions do improve road safety, since they discourage drivers from being aware of what is going on around them and thinking.
"The car will take care of that for me"
Like the one parked on the roof of the following one in the middle of a five car pile up in the fast lane of the M6?
Or the Merecedes that ploughed, at great speed, into the column of slow moving traffic ahead of it, shown recently on TV? He claimed that his brakes failed,
So did his eyes, by the look of the film! If he had been looking far enough ahead for his speed, he could have lifted off, possibly changed down and applied the parking brake to slow.
NO, that would have implied thought about what he was doing!
Twice, I have been nearly run off the road, by a driver who forgot that he was alongside another vehicle, and decided to change lanes!
I'm prejudiced, having passed a driving test where you had to halt a vehicle with an unsynchronised gear box using hand brake and gears!
