  We derive a standard Lorentz code (SLC) of motion by exploring rigid double
transformations of, so-called, 'master space-induced' supersymmetry (MS-SUSY),
subject to certain rules. The renormalizable and actually finite flat-space
field theories with $N_{max}=4$ supersymmetries in four dimensions, if only
such symmetries are fundamental to nature, yield the possible 'extension of
Lorentz code' (ELC), at which the SLC violating new physics appears. In the
framework of local MS-SUSY, we address the inertial effects. We argue that a
space-time deformation of MS is the origin of inertia effects that can be
observed by us. We go beyond the hypothesis of locality. This allows to improve
the relevant geometrical structures referred to the noninertial frame in
Minkowski space for an arbitrary velocities and characteristic acceleration
lengths. This framework furnishes justification for the introduction of the
'weak' principle of equivalence, i.e., the 'universality of free fall'. The
implications of the inertia effects in the more general post-Riemannian
geometry are briefly discussed.
