Apparently crumple zones dont really exist
A crumple zone on a car, only works if the people in the car are restrained. If the car comes to a stop, and they don't...... they're still going just as fast as they were, and will come to the same complete stop as the car. It's that sudden stop at the bottom we keep talking about.
The seat belts, the air bags, the telescoping steering column, the safety glass, the roll cage, the design of the seats themselves, and the padded dash all work with the crumple zones to reduce the gee loading -- they spread out the time it takes for the occupant to come to a stop. And the people in the car still come out with serious bruising where the belts restrain them, and burns form the air bags (if not shrapnel). Injuries are a LOT worse, without seat belts in use. All that padding and energy control goes right out the window. Most people that die in car accidents are the ones who get ejected from the car...... and that's 99% of the time because they weren't wearing a seat belt.
This is why it is so important to put infants and small children into car seats...... a 25 MPH impact with a wall will make them hit the dash, or the seat back, or the windshield just as hard as if you had tossed them out of a second story window.
No car surrounding you....... no crumple zone. Just your body. Back to the statistics -- almost all motorcycle impact accidents occur at < 30 MPH. The person operating the bike didn't account for all the variables, and couldn't scrub off enough speed, or maneuver the bike to avoid the impact. A glancing blow is far more survivable than a direct impact with a stationary object. That might
only cost you a few broken bones.
If the impact speed exceeds about 40 MPH, it doesn't matter how good the safety gear is........ odds of survival go down drastically. A 3- 4 story fall.
You can't wrap yourself in enough bubble wrap to slow your body enough to survive that. Way past 200 gee.
