Nicely worded Dave, and I honestly mean that and am not being sarcastic. I was always a fan of Winston Churchill quips and appreciate how he used to politely insult people without them realizing it until later when they had time to think about what he had said. This sounds much like the way that he would state that what someone is claiming is a lie, or at least insinuate that it is a fabrication, without actually stating it.
In my defense I made no attempt to present any of the contents of my post as factual, nor did I make any claim that any of it was based on my personal experience. I was intentionally very clear that what I wrote was what was told to me, so yes indeed it is all hearsay. I also thought that I was being very clear that what I was describing was all related specifically to one vehicle brand only, very late model Nissan vehicles, so no broad industry swipes were intended or implied. My newest vehicle is a 2018 and it is devoid of all of this stuff. For clarity I admit huge ignorance of what technology is present in any new vehicle of any brand, not just Nissan.
Apparently some can and some can not. I was told by my Brother, so all hearsay again, that some of these things can be disabled but not turned off. This means that he has to do it every time that he starts the vehicle if he doesn't want these things annoying him. In his case this can be many, many times during one day. His seem to be that he has to keep disabling stuff over and over again or he can just start the vehicle and go and live with the functions that he finds annoying being active. With some of these functions he has found that both of these choices have become very annoying over time.
