Distance illusion: For various types of vehicles on the road, drivers sometimes have illusions about the length of the arriving car, the distance between cars, and the distance with the car. The distance between the car and the car is too close to cause the accident. . The common ones are: the same distance, the daytime looks close, and it feels far away when the night is darker; the front is the distance when the cart is far away, and it is the distance when the trolley is far away.

Speed ​​illusion: Most of the drivers in the process of driving are based on the observation of the movement of the object as a reference to estimate the speed, and are not completely determined by the indicator of the vehicle's own speedometer. Roadside scenes tend to overestimate the speed of the vehicle for a long time. When the scenery is low, it is easy to underestimate the speed. After a long period of time, the speed will be adjusted to the speed, and the rest of the speed will be easily miscalculated. In particular, it is very dangerous to misunderstand the high speed. It is for this reason that motor vehicles are driving from the suburbs into the city and are prone to rear-end crashes.

Curvature illusion: How fast the driver is driving on the highway, often changing with the curvature of the road. The degree of shifting can also create illusions. Generally speaking, for a circular arc that does not exceed a semicircle, the radius of curvature often felt by the driver is always smaller than the actual radius of curvature. The shorter the arc length is, the smaller the radius of curvature is. Driving on a continuous turn of the mountain, the driver will feel that the mountain is easier to turn than the plain, so it is dangerous to make a sharp turn at high speeds while driving.

Color illusion: In the complicated traffic sections such as urban areas, the surrounding scenery is colorful and interlaced, which easily distracts the driver's attention. Especially at night, it is easy to use the traffic light as a neon light; the tail light of the stopped vehicle is used as the rear light of the driving vehicle; The brake lights in front of the car are mistaken for tail lamps. In addition, when wearing sunglasses in summer, it is easy to “filter out” light-colored objects, creating an illusion.

Light illusion: The sun, the light of the reflecting object, the headlights, and the high beam light at night will make the driver's vision difficult to adapt to, such as the bright windows of flat cars, the shadows of trees alternately under the sunlight, The reflection of snow on the field, the change of light when entering and exiting the tunnel, etc., all make the driver dizzy and cause illusion of light, resulting in operational errors.
