sir, why a moving car in zig zag way is said to be two dimensional motion ?

Dear Student
                         
                                            When a car moves in zig zag way on road then its coordinates (say x and y) change with time.In two dimensional motion, motion takes place along two axes and in this manner both x and y coordinates change with time. Hence a  moving car in zigzag way is said to be two dimensional motion.
