1. A control device comprising:
a controller controlling a first vehicle, the controller being configured to:
estimate a degree of concentration of a driver in the first vehicle during traveling of the first vehicle based on a first distance between the first vehicle and a second vehicle traveling in front of the first vehicle, a second distance between the first vehicle and a third vehicle traveling behind the first vehicle, and a relationship between a vehicle speed of the first vehicle and a predetermined vehicle speed, and
execute a vehicle control of recovering the concentration of the driver based on an estimation result,
wherein the predetermined vehicle speed is a speed limit on a road on which the first vehicle is traveling, and
wherein when the first distance is large, the second distance is narrow, and the vehicle speed of the first vehicle is below the speed limit, the controller is configured to estimate that the concentration of the driver is reduced.
