In order to cover the long distance with as little consumption as possible, the driver wants to drive in a platoon as much as possible. To do this, the driver starts an application (or "app") implementing the device 100 in the infotainment system and enters the search criteria (e.g. route, driving experience) for an optimal platooning partner.

In addition, he reads the information on the driving experiences and the kilometers driven in the platoon of the drivers involved. He weighs the possible consumption savings, which are also shown to him by the app, in the platoon with the journey alone.
