Going by the picture of the car it only looks like a miracle saved both of them and they survived.
The boyfriend and Bethany both suffered injuries to their bodies, but the boyfriend got away with recoverable injuries. Bethany seemed to bear the brunt of the force in the accident. The most horrific and serious injuries happened to her legs which she had put up on the dashboards.

As you know, in an event of an accident and collision, the cars are designed to deploy airbags in order to save the passengers from getting hurt by the dashboard and the steering.
Bethany’s legs bore the maximum impact and led her to suffer several dreadful injuries that she will now live forever. Due to the impact of collision, the airbags in the car deployed at over 200mph. In a normal crash, this is enough to affect minor injuries. But if you were sitting like Bethany, the injuries were more serious.
