A dimensionally adjustable vehicle, which comprises a platform of pivoting and non-pivoting plates arranged such that the spacing between a pair of the non-pivoting plates is changed to dimensionally adjust the vehicle upon application of an initiating force to a plurality of the pivoting plates which causes a pivoting motion. A section of the platform includes a pair of laterally adjacent and laterally pivoting plates which is interposed between a pair of the non-pivoting plates such that a lateral side of each of the laterally pivoting plates is pivotally connected to a lateral side of an adjacent non-pivoting plate. Application of the initiating force the pair of laterally adjacent and laterally pivoting plates causes a lateral dimension of the vehicle to be adjusted.
