First, recall the facts. This is the collision, High Speed, the car carrying Princess Diana with a tower that caused his death.
The protective wall is too low, the bumper hit a pylon, abruptly stopping the vehicle.
Watch below the same type of tunnel. But, protected with a high wall which prevents sudden stop pylons and… mortal!
A wall higher than the bumper, and along the front of the vehicle, allows vehicles to stop at a greater distance in the event of impact, thus avoiding a sudden stop and… mortal.
