I didn't even know this. And it just adds to the example, especially because the boat part is flat out incomplete, with steering wheels behaving either way, and straight rudders, and motor / rotor control so you don't need to use the wheel to park a motor boat. The more you look into this example, the more complicated and confusing it becomes.
