Embodiments are disclosed for an example vehicle-to-vehicle communication system. The example vehicle-to-vehicle communication system includes a user input interface configured to receive a user input, an inter-vehicle communication system capable of communicating with a navigation system of a second vehicle, a processor, and a storage device storing instructions executable by the processor to receive a first separation from the user of the first vehicle, the first separation being input via the user input interface. Responsive to receiving a first separation from the user of the first vehicle, instructions are further executable to determine a space cushion between the second and first vehicles, the space cushion being determined based on one more of the first separation and a second separation communicated from the second vehicle via the inter-vehicle communication system, and adjust a distance between the first and second vehicles based on the space cushion.
