I agree. A head-physics system would be an improvement. The same effect works for driving.
Here it is to the extreme.
More Normality looks like this.
Here is the editable code for it. HeadMass=2.5 // Head and helmet
HeadInertia=(0.062,0.048,0.049) // Head and helmet
MinPos=(-0.06,-0.16,-0.10) // Minimum extents of position (should be negative)
MaxPos=( 0.06, 0.16, 0.05) // Maximum extents of position (should be positive)
MinOri=(-10.0,-10.0,-10.0) // Minimum degrees of pitch, yaw, roll (should be negative)
MaxOri=( 10.0, 10.0, 10.0) // Maximum degrees of pitch, yaw, roll (should be positive)
// There are three types of springs to control head movement:
//
// Sliding = spring/damper force maintains given direction relative to vehicle
// Normal = spring/damper force in direction between connection points
// FreeDamping = spring is normal, but damper resist velocity in any direction
//
// Parameters for springs are:
//
// SpringDir = direction of spring/damper forces (automatically normalized, not valid for Normal springs)
// SpringHead = connection to driver head (relative to head center)
// SpringBody = connection to vehicle body (relative to head center)
// SpringCollLen = if more than zero, spring doesn't take effect until minimum length has been reached
// SpringParams = spring rate and damper rate
Spring=Sliding
SpringDir=(0.0,1.0,-0.0) // up/down
SpringHead=(0.0,-0.05,0.01)
SpringBody=(0.0,-0.05,0.01)
SpringParams=(1000.0,225.0)
Spring=Sliding
SpringDir=(0.0,-0.0,-1.0) // forward/back
SpringHead=(0.0,-0.05,0.01)
SpringBody=(0.0,-0.05,0.01)
SpringParams=(1700.0,382.0)
Spring=Sliding
SpringDir=(1.0,0.0,0.0) // lateral
SpringHead=(0.0,-0.05,0.01)
SpringBody=(0.0,-0.05,0.01)
SpringParams=(8500.0,351.0)
Spring=FreeDamping // resists yawing and rolling
SpringHead=(2.0,0.0,0.0)
SpringBody=(2.0,0.0,0.0)
SpringParams=(63.9,1.31)
Spring=FreeDamping // resists yawing and pitching
SpringHead=(0.0,0.0,2.0)
SpringBody=(0.0,0.0,2.0)
SpringParams=(21.3,1.52)
