I just remembered of two other car technologies that are becoming more and more common-place, that I loathe. Electric parking brakes, and various gimmick gearshifters. (i.e. gearshift knobs, push-button gearshifters)
Regarding electric parking brakes, those were implemented to free-up more space on the center console, and for aesthetics. However, what happens if you can't release the electric parking brake because either the battery is dead (to have your car towed), or it just won't release for some other reason (i.e. to drive your car in the first place)?
In regards to gimmick gearshifters, they also were implemented to save space on the center console, but again, there's the issue of what happens if it decides not to work? There's also the lack of physical feel with those gearshifters, compared to how with typical gearshift levers, you know which gear you are shifting to, just by the physical feel, without having to look at it. And some push-button gearshift setups, i.e. in Hondas and Acuras, take up just as much enough space as a typical gearshift lever would. As for gearshift knobs, there's the fear of accidentally destroying your transmission by turning the knob while driving, thinking it's an A/C or volume knob. I'm sure that there's some sort of failsafe mechanism so you don't accidentally brick your transmission this way, but what if that said failsafe doesn't work?
And one form of electronic gearshifter that was used in FCA cars was responsible for at least notable fatality.
