Some car models have so many buttons on the central dashboard that it can get really confusing and even frustrating. It is almost like you need to take a special course in order to learn how to handle all of the buttons. On top of that, some cars have blank switches. Those switches are just the result of mass production. They actually have some purpose in more expensive models, whereas in cheaper models these are just blank and useless – and a reminder that you could have bought a more expensive Panamera.
