What is the risk increase of being killed if thrown from a vehicle?

Being thrown from a vehicle significantly increases the risk of fatality in a crash, with studies indicating that the likelihood of being killed in such a scenario is about 23 times greater than for those who remain inside the vehicle. This is largely due to the exposure to external dangers—such as secondary impacts with the ground or other objects—and the lack of protective features that vehicles provide, like seat belts and airbags. The data highlighting this increase emphasizes the importance of wearing seatbelts, as they effectively keep passengers secure within the vehicle, greatly reducing the chances of being ejected during a collision.
