The method according to claim 1, further comprising outputting to an operator results of the wheel alignment measurements and providing the operator with instructions on required inputs and manipulations in the form of one or more selected from the group consisting of acoustical statements, optical statements, and voice statements. 9. The method according to claim 1, wherein the wheel alignment measurement is carried out on a platform hoist, the platform hoist is controlled by the central computer. 10. The method according to claim 9, wherein a plurality of level inputs to control the platform hoist are stored in the central computer, the plurality of level inputs are specific to an operator. 11. The method according to claim 9, wherein movements of the wheel and movements of the platform hoist are effected in response to a clearing instruction issued to the central computer. 12. An apparatus for performing wheel alignment measurements on wheels of a vehicle, comprising:a central computer to control execution of the wheel alignment measurements using a wheel alignment program; anda machine operable by a machine control program included in the wheel alignment program, to turn and to position the wheels of a steerable axis of the vehicle to positions required for the wheel alignment measurements, whereinthe machine control program includes a plurality of control procedures for automatic positioning the wheels including any of the procedures for positioning the wheels to “drive straight ahead”, for automatically turning the wheels to the left and to the right, for automatically positioning the wheels to “single track left” and to “single track right”, for turning the wheels to a maximum angle, and for maintaining the wheels at 0°. 13. The apparatus according to claim 12, wherein the machine control program is provided either in the central computer or in a microprocessor in the machine whereby the machine is controlled by the central computer or by the microprocessor in the machine. 14. The apparatus according to claim 12, wherein the machine is located between a steering wheel of the vehicle and a fixed point on the vehicle. 15. The apparatus according to claim 12, further comprising a steering wheel level device on a steering wheel, the steering wheel level device coupled to the central computer or the microprocessor to output information on a zero position of the steering wheel to the central computer. 16. The apparatus according to claim 12, wherein the machine further comprises a motor-driven turntable platform on which the wheels along the steerable axis stand during the wheel alignment measurements. 17. The apparatus according to claim 12, further comprising a plurality of interface devices to wirelessly transmit data and commands between the central computer and the machine. 18. The apparatus according to claim 12, further comprising a remote control to send a clearing instruction to the central computer to enable operation of the machine. 19. The apparatus according to claim 12, wherein the wheel alignment measurements are carried out on a platform hoist in response to a control device, the control device comprises an interface device to transfer data and instruction between the control device and the central computer.
