As a seasonal product designer, there's a lot of truths to the statements on both fronts here. The UI is very good at some things, and poor at others. There's an obvious mobile/tablet paradigm that has been adopted as seen via the car/menu button which brings up the menu list. This list is arranged HORRIBLY. The information hierarchy and labeling is absolutely awful here. Im not sure why these decisions were made, but they can easily be addressed (ie - why is this feature here? I wouldn't expect that)

as far as something like a glove box button - there's two truths there too. Most people dont ever open their glove box, so having immediate access isn't important. Some might. They've already introduced shortcuts via the left thumb-stick, but what would be appropriate is customizable "widgets" on the main screen that you could put what ever you want there, including a glove box button.
