• a fourth wheel coupled to the vehicle body, and
• the vehicle being capable of traveling in a predetermined direction using the first wheel, the second wheel, the third wheel, and the fourth wheel,
• the vehicle body including:
• a floor surface portion and a ceiling surface portion arranged along the predetermined direction;
• a left side surface portion connecting the floor surface portion and the ceiling surface portion and arranged on a left side surface along the predetermined direction;
• a right side surface portion connecting the floor surface portion and the ceiling surface portion and arranged on a right side surface along the predetermined direction;
• a front surface portion connecting the floor surface portion and the ceiling surface portion and arranged in a front portion along the predetermined direction;
• a rear surface portion connecting the floor surface portion and the ceiling surface portion and arranged in a rear portion along the predetermined direction;
• at least one front seat disposed closer to a front surface portion side than the rear surface portion on the floor surface portion;
• at least one rear seat disposed closer to a rear surface portion side than the front surface portion on the floor surface portion;
• and
• a transparent display disposed between the rear seat and the front seat, having a first display region capable of outputting a video of a first shape, and including a variable light transmittance sheet,
• the variable light transmittance sheet corresponded to at least the first display region, being disposed on at least a front seat side, and having a variable light transmittance, and
• the vehicle control method comprising:
• when outputting a video including a second display region having a second shape in the first display region,
• setting the variable light transmittance sheet to include a light-shielding region having a third shape and a transmission region having a fourth shape other than the light-shielding region, the light-shielding region having a first light transmittance, and the transmission region having a second light transmittance larger than the first light transmittance, and
• setting at least a part of the light-shielding region to overlap with the second display region.
