driving force Gt does have an optical sensor, which can come loose from the gear shaft it sits on because of three shallow cuts in the optical wheel that make it crack and go loose. just happened to me and found fix online. easy enough to get to and if you carefully glue it to the shaft its fixed. don't use superglue as i did, it blocked up some of the slits in the wheel.... now need to find a replacement optical sensor wheel.
