A sensor for sensing the operation degree of an accelerator in a car is disposed and a display device whose light emission display extends and contracts on the basis of detection of this sensor is disposed on the car to face outward. There is also disposed means for detecting both the number of revolution of an engine and the number of times of operation of a brake pedal so that the number of revolution of the engine and the number of times of operation of the brake pedal can be displayed and known by light emission with the operation degree of the accelerator both inside and outside the car. Furthermore, there are disposed car running speed detection means and car acceleration/deceleration detection means, character strings having a plurality of mutually different meanings are displayed outside the car to display its running state in accordance with the detection state of these detection means. The car body moving direction is displayed outside the car on the basis of the rotating direction of the handle to the right and left and its degree of rotation. |
