It is reported that this kind of operation can make the passengers leave the collision vehicle in time and quickly, thus avoiding or reducing the casualties when the vehicle is hit by a huge impact.
I think it's a gimmick, and it's basically useless. There are two main reasons for this view: one is from the perspective of safety, and the other is from the perspective of follow-up treatment.
From the safety point of view, because the car is driving on the ground, it is completely different from the ejection function of the plane. If the car is out of control before the collision, it may cause more serious consequences, but if it is ejected during the collision, the collision time is often very short, which is not only a question of whether it can be ejected successfully, but also a safety issue after the seat is ejected.
If the ejection height is too low, the threat of traffic accidents may not be avoided, but if the ejection height is too high, ordinary people's bodies simply can't bear it. From this perspective, this function is undoubtedly a chicken rib.
From the point of view of subsequent processing, it is difficult to control the setting of vehicle collision intensity. Originally, if the accident was not very serious, wearing a seat belt could completely avoid serious injury or death, but if it was ejected, the whole follow-up was handed over to God, and neither the driver nor the passengers could effectively control it.
For ordinary drivers and passengers in life, if they obey the traffic rules and fasten their seat belts during driving, life-threatening traffic accidents will generally not occur. But if such an accident happens, the so-called high probability ejection seat will not play any role.
