The worse case, the vehicle get airborne and plants either the nose or tail. Are the vehicles being built for this type of deceleration event? Everyone think of a lawn dart.
I believe Ed said it, about it is a Total package, Seat, Hans, belts, padding in the correct places etc, etc etc.
I am new to this . But, please not the Proster. I have read some of that trivel.
Lets not reinvent the wheel here.
LSR vehicles are just that, a vehicle in motion. LOTS of studies have been done, look at the design changes in F1, indy and yes Neckcar!
The dymanics of the deceleration event have not changed.
