Claim:
A vehicle disposed upon a surface, said vehicle comprising: (a) a plurality of rear wheels, each having an axis in alignment with the other, thereby forming a rear axis line; (b) a first front wheel assembly comprising: at least one first front wheel; a first front wheel axle forming a first front wheel axis; a first steering column rigidly coupled to said first front wheel axle and substantially perpendicular to said surface; and a first steering drum rigidly coupled to said first steering column; (c) a second front wheel assembly comprising: at least one second front wheel; a second front wheel axle forming a second front wheel axis; a second steering column rigidly coupled to said second front wheel axle and substantially perpendicular to said surface; and a second steering drum rigidly coupled to said second steering column; (d) a first cable affixed to and leaving said first steering drum from a counterclockwise direction proceeding through a first path and then to counterclockwise around said second steering drum and affixed to said second steering drum; (e) a second cable affixed to and leaving said first steering drum from a clockwise direction proceeding through a second path and then to clockwise around said second steering drum and affixed to said second steering drum; and (f) a means by which at least one steering drum changes and controls a length of said first path and a length of said second path such that a sum of said first and second path lengths is substantially constant and a ratio between said first and second path lengths is such that said rear axis, said first front wheel axis, and said second front wheel axis intersect at a single point regardless of a rotational direction of the at least one steering drum.
