The car should have slowed at that six second mark, and at least reduced speed dramatically by the time of impact (if not completely).
The risk of fatality would have been severely reduced if the car was (at most) travelling at 30mph (likely around ~10% - instead of between 25% and 60% for the speed at the time of impact depending on what study you choose).
