I was thinking why not make cars like cars, not smartphones. I hate when a car after a number of years is still perfect except for the extra bells and whistles.
The lane assist and brake assist - along with adaptive cruise control - are great systems that also increase safety, if used properly. The difference in fatigue alone that these systems contrubute to is (anecdotally from my experience) night and day.
I believe that the improved safety is worth the increasing complexity of maintenance.
