Adding on to a bit from your comment that I missed, it’s not affecting the car itself. The article should have used the word “phone” instead of “device”.
All Android Auto is a screen for your phone that also hooks into car buttons. Your phone does all the hard work with projecting data to the screen. If your phone is too old, Android Auto might not work because apps don’t work properly with the base framework by Google.
You can use a new phone on an older car that officially supports Auto/CarPlay. That’s never been a problem.
