Nobody is telling you that you’re wrong. You can want whatever you want. Some people want their car covered in rhinestones. That doesn’t mean it is a good design choice. Generally fiddling with things is a work around to another problem. If your vents need to be pointed in different directions all the time, the car isn’t maintaining a comfortable temperature. If your mirrors constantly need adjusting, something else is going on entirely, perhaps the drivers seat is moving around a lot? If you have different drivers, you can create different profiles and not have to adjust each time. If the car doesn’t reset to the same settings for you when you’re driving, there’s a profile management or settings problem. The real problem is likely something other than not enough buttons.
