There us far too much unnecessary tech/toys in new cars.
It is a distraction in that it entices more “eyes off the road” to make adjustments and is, as pointed out, just a variant to mobile phone use whilst driving.
The myriad safety functions create a feeling of invincibility in that the car will get you out of a bad situation. Drive like an idiot ...the car gets you out of trouble so do what you like. There are some that should be mandatory such as ABS type systems. I drove a Nero hybrid courtesy car the other day just home and back to garage later. I found the display screen a distraction with its battery level monitor like a magnet and had to consciously ignore it.
Electric seats (adjustable and heated) . Why? Excessive tech, cost, weight. Lots of buttons on the steering wheel, it reminded me of an F1 steering wheel. Why? The ones I use on my Sportage are radio volume and cruise control. It has TPMS that might be useful. The phone link ones? Never. There is even an indication of which gear I should be in. Really? Same with the info computer. Instantaneous mpg? Multiple options for things I never use or need. Trip meter is ok occasionally. Miles left (range) based on petrol in my tank? Never used. On an EV that might be useful!
I must admit I started to question the need for many gadgets, refinements etc when Mercedes first introduced double glazed windows in the S class.....I do struggle with manufacturers producing inherently undriveable poorly balanced fast cars which requires a significant reliance on driving aids.
