A story of disappearance: First, the car's switches, buttons and rotary controls made off.

Electronic displays replaced mechanical controls.

In the beginning there was only one on-board monitor on the dashboard, today there are up to three.

Hundreds of functions can no longer be triggered with switches or rotary controls.

The touch-sensitive display, while not loved, is essential.

The story of the disappearance and the reduction to pure software is by no means over.

Next to disappear are Mercedes-Benz, Audi, Porsche, Jaguar and Nissan.

Your infotainment software becomes redundant.

Automakers can still install screens, but things are looking bleak for apps.

"Hey Mercedes, what's your future?",

we recently asked the language assistant in the new C-Class.

The answer came smugly, quietly, almost incomprehensibly.

We heard something like "Carplay" and didn't know what to do with it.

Since last week's Apple developer conference, things have been clear: Carplay, the iPhone infotainment system for cars, can in future be used on several screens in the vehicle and will set the air conditioning or display the speedometer and rev counter.

Carplay merges with the vehicle and becomes the car's operating system.

One can only wonder that said car manufacturers want to participate.

They have invested billions in the development of their own software and are now voluntarily handing over their customer window to outsiders.

It can't be that.
