I don't want to start an argument with you. Just stating my opinion.
Obviously there is no direct citation, quote, published data that I know of.
But there IS empirical evidence:
Look at the new cars out there. How many have the new "tech" ? How many don't?
I don't know the exact data. But if you walk around the new car lot, you'll get a good sense of the data.... which is the empirical evidence.
Aren't forums a way to have civil arguments with peers so that we can share our opinions?
Again, you are confusing a decision that was made by marketers and board members concerned with maximizing profit and thinking it was actually a reflection of consumer demand. The fact that more cars on the lot have tech is not due to consumer demand, it's due to executive decisions at car companies that only want to make more $$, not do you favors or improve your life. The reason why all the companies are putting tech into the cars is because they can charge more per unit, and the unit will need to be replaced sooner. It's not because the technology is what makes a car function or desirable for all or a majority of consumers. It's a novelty, a luxury, that some may decide to pay an increased cost for.
Also you are not considering what a rational actor who looks at the full cost and benefit of the tech.
If you asked rational people if they wanted more technology in the car then the majority might say yes.
If you say that there are downsides, such as failures, faulty screens, lag, or essential controls routed through the technology that may be vulnerable to failure then I'm sure a lot less would demand this tech.
If you say that this technology will also make cars depreciate more, and be outdated in 2 years time, and maybe not even capable of updating (like slowed down iphones), then I'm sure even less would demand this tech.
If you say that this will also increase the cost of purchasing, cost of ownership, cost of repairs, I'm sure your pool of rational customers would get smaller.
The car companies are only doing the former, they're only advertising (see-brainwashing) you to believe that the technology is only to your benefit when it's actually to theirs.
