When I was a kid there were toy RC cars that had two controls, kind of like 1-axis joysticks. The left one pushed upward would cause the car to go forward, possibly with more or less power. The right one pushed to the right allowed turning to the right (but not the left, like Zoolander). A consistent upgrade to this interface would be to allow reversing using the left control in a downward direction and turning left using the right control pushed to the left. An inconsistent application would be to have reverse on the right control pushed to the left and left turning on the left control pushed downward. Inconsistencies across classes are not uncommon and probably understandable given various expectations. For example, the same handlebar steering control behaves very differently on a two-wheeled motorcycle compared to a tricycle.
