1. A self propelled vehicle comprising a chassis structure, at least three ground engaging wheels mounted on said chassis structure, at least one of said wheels is directionally controllable, powertrain means mounted on said chassis structure and coupled to at least one of said wheels, braking means mounted on said chassis structure and coupled to at least one of said wheels, and a control element rotatably mounted on said chassis structure and coupled to said at least one directionally controllable wheel, wherein said chassis structure comprises at least one suspension structure, each suspension structure has at least two of said wheels mounted thereunder and at least one pair of the mounted wheels are positioned side by side to provide lateral stability, a pivoting structure with room for at least one passenger, and at least one pivotal means for mounting said pivoting structure to at least one of said suspension structures such that the effective pivot axis of said pivoting structure relative to the ground is along its longitudinal axis and projects above its laden center of gravity thereby hanging at least a section of said pivoting structure from the ground whereby gravity will urge said center of gravity downwards and will maintain said pivoting structure in a substantially upright position whenever the vehicle is stationary or traveling in a straight path and centrifugal force will urge said center of gravity outward of the turn and tilt said pivoting structure inside the turn whenever the vehicle is turning.
