To design a car that does not deform in an accident is easy, exhibit A = Nissan Patrol. At low speeds you are OK, as you will be in almost any car - other cars will have significantly more damage.
Noted. D Ladder frame chassis vehicles generally get poor NCAP ratings?
What is the Patrol's rating?

Not nice to hear of such things.

Do you have the working inserts in the upper back lights or only the bumper ones?

I have heard that the extra brake lights "wake up " the tail huggers better and can help avoid accidents.
I effectively have five breaklights.
Four of them go on with the head lights, with the extra bulb igniting on break.
Two in the steel bumper corners and two in the body (after market activated)
And one at the top of the larger rear door only activating on break.
So that should have been enough for the tail hugger.

Anyone with an alluminium central rear step lying aroudn at home?
Those of you that have recently replaced the entire rear bumper perhaps?
I still use this section as I only have steel corners (as seen on the picture)

The alluminium central rear step costs aroudn 5k from Nisssan!
I can get it through insurance, but as a matter of princiople I do not want to do that.

Also, can someone perhaps pm me Dawid Volschenk's contact details.
He may have a remaining left tail light for me. Mine is cracked.

Lexi .. hier by die Chaina sjop naby ons is kompleet agterligte vir jou model Trol -- wat gemaak is vir LED liggies [vrek goedkoop] het gesien toe ek THOR gery het en paar goed daar wou aanskaf. [Laasjaar was onder R1,000 vir die twee .. kompleet ligte [lense, glas, draad .. ]
Kom kuier - dan vat ik jou soontoe .. en dan plan ons sommer die volgend 4x4 4 Kids..

David se nomr nul-agt-drie 499 een-vyf agt-agt. Ek dink hy het vir jou bumper middelstuk ..

Yes, since it is a monstrously sturdy and rigid frame that stretches from back to front. There is very little in the way of energy absorbtion and the passenger is exposed to the full deccelaration forces of the impact. A function of the speed at which the impact happens. The injuries are not so much blunt trauma as it is damage to organs exposed to the G-forces. Hence the airbag is not of so much help.

A car with good crumple zones, engines submarining under the body etc, allows the occupant to slow down at the slower rate, since relatively the passenger is still moving forward whlst all these deformations are taking place.

The ladderframe chassis is rigid and causes evrything to stop. right there and then, not much happening in terms of deformation and energy absorbtion.

However, the lack of safety provided by the rigid chassis should just be compensated for by your primary safety feature - the operator!

Alex, bly julle is OK.

Just as an aside, I have often wondered wheter the solution to crash safety in ladder-frame vehicles is to have body mounts that shear easily in forward/backward direction, but are robust in a sideways direction...

From the point of view that if you run into something solid, the chassis with axles, engine, drivetrain etc. (and thus most of the momentum) would stop, and the body with crumple zones and safety cell could continue and bsorb it's own momentum, but in a roll or T-bone, everything would stay together.
