On January 24, the author learned from relevant sources that a four-car rear-end traffic accident occurred on the Shanghai Inner Ring Viaduct, and one of the red Tesla Model 3 "burrowed" into the bottom of a BYD Song Pro DM and lifted the latter high.

Judging from the scene, the front load compartment and headlights of the Tesla Model 3 are more seriously damaged, and the front windshield also has crack marks, but the A pillar has not been deformed. The damage to BYD Song Pro DM is still unknown.
According to the news on the Internet, it is suspected that Tesla Model 3 turned on the driving assistance function at the time of the incident, and the following distance was only set to "1", which represents the time when the Model 3 arrived at the bumper position of the front car, reflecting that the braking time is slightly shorter, so when the current car suddenly brakes suddenly, it may collide due to lack of time. In addition, it is worth mentioning that some media reported that the airbags of Tesla Model 3 and BYD Song Pro DM that occurred in this accident were not opened.
However, although this is a rear-end accident, the cause and the final determination of responsibility will not be known until the relevant law enforcement departments investigate, and the author will continue to pay attention to the follow-up progress.
