I honestly think it's a shame that car companies have convinced a lot of people that some of these automated features are "must haves" in luxury cars, when in reality they provide little actual value to the driver.
I totally agree with what some others have written about Highway Assist - it's a really "neat" feature, but considering I don't really trust it 100%, and I have to have my hands on the wheel at all time, it doesn't really make my drive any easier. And this goes for other versions of this in other cars.
I'll give another simple example. The ultimate "first world problem" I know, but I hate auto windshield wipers. Reason being where I live we often get light, "misty" rain, and auto wipers suck at this - by the time they turn on my windshield is covered with rain drops, so I always need to flick in manually anyway. My point is that I think "old school" wipers with low, medium, high and, importantly, adjustable intermittent speed, worked better in every way. I feel that auto wipers are basically a "parlor trick", and now they are almost expected on high end vehicles because they are more advanced tech, but, at least for me, they provide a far worse experience.
