1. A vehicle with a driving environment risk determination apparatus comprising:

  • a communication unit configured for vehicle-to-vehicle communication;

    one or more sensors arranged to detect driving environment information in the vicinity of the subject vehicle; and

    one or more controllers, configured to;

    acquire a status information of a driver who drives another vehicle running in the vicinity of a subject vehicle that is equipped with the driving environment risk determination apparatus via a vehicle-to-vehicle communication with the another vehicle by the communication unit, wherein the status information of the driver who drives another vehicle includes information on at least one of a facial expression of the driver of the another vehicle, a body temperature of the driver of the another vehicle, a degree of sweating of the driver of the another vehicle, and an operation condition of one or more of a brake pedal of the another vehicle, an accelerator pedal of the another vehicle, a steering wheel of the another vehicle, and a blinker control of the another vehicle by the driver of the another vehicle;
