That's crazy. Assuming the car weighs 1300 KG and decelerated at 788 Meters per second squared (based on the deceleration time of 68 milliseconds), that's 230,294 pound-feet of force or 1,024,400 Newtons.
If you imagine one Newton is the force needed to accelerate a mass of one kilogram one meter per second per second, or it can push 2.2 pounds to a speed of one meter per second every second, in this case, that force could accelerate 2.25 million pounds to a speed of one meter per second every second, that's a brick ton of force!
If you imagine one Newton is the force needed to accelerate a mass of one kilogram one meter per second per second, or it can push 2.2 pounds to a speed of one meter per second every second, in this case, that force could accelerate 2.25 million pounds to a speed of one meter per second every second, that's a brick ton of force!

From what I remember, Earnhart's car went into the wall at an angle, wrenching his neck sideways and breaking it. He also refused to follow his Crew Chief's advice and wear a special helmet-brace system because he claimed it was too uncomfortable. Now, drivers can't refuse any more...NASCAR has mandated them. You either wear them or you don't race.
