A vehicle 10, for example a golf buggy, has a steering system 24 which includes a control means 26, for example a joystick, operable to receive a user instruction 28 indicating a desired direction of travel. Control means 26 provides control outputs 30 for drive arrangements 32, typically electric motors which may be provided at each wheel 16, operable to drive the ground wheels 16. Control outputs 30 include drive information for wheels 16, causing vehicle 10 to be turned by the relative speeds of wheels 16 to either side 34, 36 of vehicle 10. The relative speeds may be varied to vary the rate of turn, and outputs 30 may include speed and/or braking information and may provide regenerative braking. Optionally, wheels 16 on opposite sides may be drivable in opposite directions to cause the vehicle to spin.
