Airbag, seatbelt with pretensioner, rigid cabin, and some crumple zone is all it takes to survive a crash below that speed.
For a healthy, non overweight person, below 40, survival rates already close to 85%-90%.
The reason I'm ringing an alarm here is that survival rates began to slide back since mid naughties exactly because of the trend for more heavier cars being marketed as "safer" resulting in more violent car to car collisions, and more cars going through road barriers.
