Abstract: A vehicle controller is used for a first vehicle and includes processing circuitry. The processing circuitry is configured to execute an index deriving process that derives a traveling performance index of the first vehicle, the traveling performance index being an index related to a traveling performance, an index receiving process that receives the traveling performance index of a second vehicle from the second vehicle through vehicle-to-vehicle communication, and a performance determination process that compares the traveling performance index of the second vehicle with the traveling performance index of the first vehicle to determine whether a traveling performance of the first vehicle is lower than a traveling performance of the second vehicle.

Abstract: A vehicle lamp has a light guiding body having a light guide section having a dimension in which a dimension in one direction perpendicular to an optical axis of the light emitted from the light source is smaller than a dimension in other direction perpendicular to the optical axis and the one direction, an incidence section that causes the light emitted from the light source to enter the light guide section, and an emission section that emits the light guided inside of the light guide section to outside of the light guide section, the shade has an opening section through which light that has entered the incidence section passes, and at a cross section in the one direction, the optical axis is located at a position offset toward one side in the one direction with respect to a central axis of the light guide section.
