In which scenario is ejection likely to occur during an accident?

Ejection during an accident is most likely to occur in rollover scenarios. This is largely due to the nature of rollovers, where the vehicle's orientation changes dramatically, and during the tumbling motions of the vehicle, occupants can be thrown out if they are not properly restrained by seatbelts. A rollover often involves impacts from multiple angles or forces that can lead to the doors being compromised, further increasing the likelihood of ejection.

In contrast, low-speed collisions tend to not generate enough force to cause occupants to be ejected from the vehicle. Front-end crashes and side-impact collisions can certainly be severe, and while they pose a risk for serious injury, occupants are generally more likely to remain within the vehicle if they are wearing seatbelts and if the vehicle remains structurally intact. Rollovers, with their unpredictable motion and associated factors, pose a heightened risk for ejection, making it the correct context for this question.
