In some circumstances 4g is deadly (human resistance to negative vertical g-force is lower than that), in other hundred of gees can be survived. G number alone says nothing.
In fact even 1g can kill you, e.g. when being suspended for a long time in inapropriate safety harness.
And it is not enough that the device is safe enough for average person. It must be safe for practically anyone that gets in. Rollercoaster users do not go the same health checks and training as fighter pilots (yes, they are trained how not to get killed by g-force).








To have something to attach the bribe to.
