Internal decapitation happens quite a bit.
I think there is something with the individual, however. I have been in all kinds of accidents and walked away from them. Like I can take a beating pretty good. |

Yes, but usually they get crushed, or something slides over them (or parts of them) which also causes crushing and severed arteries via slicing action. The ones not wearing seatbelts usually get ejected, and die from impact with a heavy stationary object, or another vehicle, or the vehicle they were in tumbles over them. View Quote So, on impact, you start leaning forward, the air bag deploys, hopefully you are restrained from hitting the wheel and collapsing it into the dashboard. If forces are high enough, tho, your pelvis is dragged out from under the lap belt by your legs, which bend at the knees driving them up under and behind the dash into the A/C ducts etc. This pulls your hips down to the floor while it's rising up from the engine raising it as it moves back and downward, straightening the path for the rest of you. Your head winds up looking up at the brake pedal while the rest is folded up under the dash multiple times. Hence the Jaws of Live to separate the firewall from the floor pan to pull you out, unfolding you. In the process, numerous broken bones in close proximity to blood vessels are slicing you up, damage to your skull has created exit wounds for insanguination, and if you are still conscious, you might realize there is no way rescue personnel will get there in time. Unless you actually hit an ambulance pulling out of the station. If a gunshot wound can cause you to bleed out in less than three minutes, response times of 15-25 aren't really going to do any good. Your dead, Jim. Absent a full roll cage and submarine belt, you won't survive a collision at 70. That's often a combined speed of 140 with another vehicle. Humans are not capable of surviving falling 34 feet, which is all it takes to achieve free fall, and it's the stop that causes the damage. About 95 - 118 mph, but there are those who deliberately achieved breaking the sound barrier. With a car body around you - don't forget, that mass can't decelerate faster than you, it drags you with it - we get some minimal protection, but if you plan to survive, then avoidance is your primary tactic. Go surf interior cams of drivers in collisions and how people bounce around and flip right out of the cab with no seatbelt. Window up, too. |

I was in a wreck from a blowout at hiway speed. We did a 180, slid across 3 lanes of traffic and sheared off the I beam post that said “Welcome to Jones Beach”. The I beam was turned into an inclined ramp which tossed us like evil knevil into a barrel roll. We came to rest after 3 or 4 revolutions on the driver side door. Lucky to survive that one for sure - I got busted up tho.
Craniums (heads) are heavy and upon rapid sudden deceleration its very easy to disconnect your spine from your brain.... |

With seatbelts?
Cabin intrusion and GeForce. An example of g's, Dale earnhardt. He died from the head whip. |

Sudden acceleration and deceleration. G forces are real. High G forces are lethal View Quote Mostly though, from what I've seen and read about, it's people doing stupid stuff that get hurt the most. Not wearing the belt properly. Laying down in the back seat. Legs not where they belong... |

Aortic tears. At scene or soon after.
I've seen 'em come in talking then, "see ya". DRT. Big tube filled with blood doesn't like to me yanked around. |

Quoted:
Aortic rupture due to G-forces/sudden decelleration. I can't rmember the #, but in a safety class they said that your aorta detaches at some incredibly low G and is the cause of death in someting like 1/4 of car fatalities. View Quote |

Quoted:
65mph to 0mph in 1 second. View Quote OP, as explained to me by the doctors...most accidents are survivable under 45-50 mph...most not all, once you go over that speed the damage skyrockets due to the amount of G-force involved..In my case going from 60 mph to zero mph in less than 4 feet..I will deal with it for the rest of my life..... |

Brain coupe & counter-coupe (brain bouncing back and forth inside your skull).

The answer is similar to what kills a person who falls off a tall building. It's not the fall, it's the sudden stop.

Sudden deceleration at the end coupled with high velocity impact (outside and inside). Organs are still going at however fast even though your outer body stops.

I survived a sideways roll over (flipped three times). Seatbelts and airbags are awesome. My primary injuries were blunt trauma or restraint induced. Broke my collar bone in two places, dislocated my left hip, severe bruising and minor lacerations. I also suffered a serious concussion. Debatable if it was trauma from the vehicle cab crushing around me or impacts from objects in the cab. I had a square shaped bruise that matched my computer that came loose from its docking station on my face. https://www.AR15.Com/media/mediaFiles/40084/CAM00118_jpg-1029621.JPG https://www.AR15.Com/media/mediaFiles/40084/CAM00122_jpg-1029622.JPG https://www.AR15.Com/media/mediaFiles/40084/20190725_064938_jpg-1029624.JPG |

Quoted:
internal organs literally rip loose from blood vessels that feed them, while they might not actually break many bones, their aorta has separated from their heart. your BMW CRUNCHING actually helped you a lot in your wreck, that crunching ate up energy that oculd hav ebeen deposited in much squishier mushier YOU. Old cars could drive away from wrecks that killed passengers, people walk away from wrecks that DESTYROY their cars. many cars nowdays have engine drop features that ditch the engine and make the entire hood area into a crumple zone, makes them destroyed in a wreck, but people walk away form said wreck.

A high speed car wreck is about the only thing in this world I'm afraid of. Its just an ugly, violent way to die and you can't predict when the fucking morons surrounding you on the road are going to try to kill you. I especially hate oncoming traffic on 2 lane roads. Long before I was born, my mother boyfriend was killed by a driver crossing the center line. He was/they were 18.

Still amazed at Dale Earnhardt's death. Video didn't look like a severe crash.

Or like my Dad used to say. "It's not the fall that kills you. It's the sudden stop at the bottom...."

Does blunt force trama come into play? The ones not wearing seatbelts usually get ejected, and die from impact with a heavy stationary object, or another vehicle, or the vehicle they were in tumbles over them. In your situation, I'd guess the sudden deceleration/stop and jerk had something to do with your back injury. I've seen just about everything. Up to decapitation of people. To a brain being thrown infront of the car and then the car run over the brain. It looked as if the head had been put in a helicopter prop. It's funny though. I've seen accidents you'd swear no one could have possibly have survived. Yet they walk away. Others with hardly any damage and they died. Pretty much everything stated here. It's not one single thing that kills. But most deaths resulted from people not wearing seat belts. Including my own brothers. He was ejected through windshield and his truck flipped over ontop of him from his chest down. It was muliple things that killed him. Not wearing seat belt, ejection, blunt force trauma (which includes trauma to organs) from going through windshield and hitting the road then crush injuries. Worst day of my life and still is. He was my only brother. |

Inertia is a bitch.
Stuff inside the human body is not designed to change directions in milliseconds, even if the distances travelled aren’t very far. Shit tears, shit breaks. That’s bad. The amount of force involved in a car wreck is ridiculous. |

Back in the early 90's I was at a one car overturn on a curvy 30 mph road. Roads were dry. Drunk kid somehow flipped the Isuzu Trooper onto its side trapping one of his friends underneath the driver side with only the lower half of his body sticking out. It looked like the Wicked Witch from the Wizard of Oz. Driver was arrested for DWI.
Another one same timeframe on a east/west 55 mph road with traffic lights. The north/south road was a 30 mph road.This one occurred at a traffic light intersection. The westbound car got T-boned by the other car who ran a red light. Female in the westbound car was ejected. Didn't appear like she had any major injuries. She died because she landed facedown in a puddle. Needless to say neither one was wearing a seatbelt. |

View Quote Transverse basilar fractures do not result from simple decelerative forces ("head whip"). Decelerative forces do cause atlanto-occipital disarticulation, commonly called "internal decapitation". The fact that some non-forensic "expert" with a built-in bias ($) reviewed a perfectly clear autopsy report and came to an incorrect conclusion because of ignorance or an agenda doesn't make it so. Those of us who do this for a living (especially those with aerospace pathology backgrounds, like the forensic pathologist who actually did Earnhardt's autopsy) see these injuries frequently. The mechanism is well-documented and by no means mysterious. BTW, as to aorta lacerations, the G load required varies somewhat with how healthy said aorta is. The numbers come from correlation with military aircraft mishaps. For relatively young, healthy males (i.e., military pilots), we start to see transverse lacerations at about 50G, and transections at 80G. Where the aorta tears is almost always at the downward part of the arch. That's an anatomically weak area, coupled with it being where the rest of the aorta is attached to the spine. Inertia during the collision causes the big heavy heart to pull on the flexible hose, and it tears at that site. |

Watch a few of these. https://www.youtube.com/results?search_query=dashcam+video+of+drivers+in+crashes
No, not hot. You have to want to see them. |

Quoted:
No, he did not. He died because his chin impacted the steering wheel. Because the jaw is an arch, force is transmitted to the base of the arch, which is where the jaw articulates with the skull (the TMJ). Fracture lines follow the line of force, i.e., from TMJ to TMJ. This results in a transverse basilar skull fracture. Transverse basilar fractures do not result from simple decelerative forces ("head whip").

A contrecoup brain injury. A contusion resulting from the brain contacting the skull on the side opposite from where impact occurs.

You are much better off being in a car made after the 2012 safety upgrades. Also, good European cars seem to be better in crashes at stopping passenger compartment inclusions. Also, that little econo-box, like a Honda Fit, isn't worth a shit when you get hit by a Suburban.

This is a great video of crashes and what happens inside.
https://www.youtube.com/watch?v=YRh3_ykQioQ The one at 3:23 is a great one. Three pax, two belted in. Third pax becomes a missile. 8:07 is another one. Wear your seatbelts people! |

Kinetic energy poisoning of one form or another.... the rest is all relative

As stated above by other it’s a combination of things. A seatbelt increases your chance of survival, but the body can only take so much. Internally is where a large amount of the damage is done.

I can't tell you how many Gs it is but an instantaneous change of velocity of 18 mph is all the speed needed to generate it. We are amazingly resilient, fragile creatures. View Quote |

Blunt force trauma, especially to the noggin. Crush injuries. Severe bleeding, internal and external.
Don’t drive impaired, wear your seatbelt, slow down and pay attention to the road. Your phone, food, etc., can wait. |
