At about 8:00 a.m. on January 24, a four-car rear-end collision occurred on the Shanghai Inner Ring Elevated Highway, and a Tesla Model 3 directly shoveled a BYD Song Pro DM due to untimely braking, but fortunately no casualties occurred.
It is understood that the cause of the accident is suspected to be that the Model 3 owner opened the AutoPilot automatic auxiliary driving function, and opened the front collision warning, but the distance with the car is set to 1 grid, in the BYD braking, due to the short reaction time, Tesla owners slammed on the brakes did not have time to brake, airbags did not come out, resulting in accidents.
It should be noted that tesla's auxiliary driving settings with the car distance, 1-7 represents the time required to reach the front bumper from the current position, the owner sets 1 Obviously the reaction time is slightly shorter, the peak period of the elevated road is still more than 3 slightly better, 1 block must not have a response time, otherwise if the front car brakes urgently, it may be too close to brake because the distance is too close.
As far as the scene pictures are concerned, Tesla is pressed by BYD, tesla A pillar is not deformed, the screen in the car can still be used, only the front hatch is damaged, and bydir's injury is not too high, and whether the motor is damaged is not known. However, the airbags are all popped up, and I don't know if they didn't collide with the position.
It is reported that the cause of the accident and the determination of responsibility still need to wait for the investigation and notification.
