1. A method of forming a monocoque of a land vehicle using a modular system, the method comprising:
forming a front cage mold unit of the modular system corresponding to a front cage of the monocoque that at least partially defines a front end of the land vehicle, and
forming a rear floor mold unit of the modular system corresponding to a rear floor of the monocoque located rearward of the front cage in a longitudinal direction that at least partially defines a rear end of the land vehicle arranged opposite the front end in the longitudinal direction,
wherein forming the front cage mold unit of the modular system comprises
producing a single mold unit,
interconnecting a base at least partially defining a floor of an operator cabin of the land vehicle and a frame at least partially defining a roof of the operator cabin as a unitary structure such that the frame extends above the base in a vertical direction, and
defining (i) a first section of the base that is overlaid by the frame and (ii) a second section of the base that extends forward of the first section in the longitudinal direction beyond the frame such that the second section is not overlaid by the frame at a forward end of the land vehicle,

wherein forming the rear floor mold unit comprises defining a plurality of cutouts extending inwardly toward one another through a body of the rear floor mold unit in a lateral direction perpendicular to the longitudinal direction such that the rear floor mold unit has a reduced width between the plurality of cutouts in the lateral direction,
wherein the front cage mold unit and the rear floor mold unit are structurally distinguishable from one another,
wherein the base of the front cage mold unit and the body of the rear floor mold unit are aligned in the vertical direction, and
wherein the frame of the front cage mold unit extends above the body of the rear floor mold unit in the vertical direction such that at least part of the frame and the body are not aligned in the vertical direction.
