Aragoto is riding along on his bike, and some rude individual shoots him unconscious. Because Aragoto is unconscious, his bike (automatic equipment) turns off and he becomes a prone S2. Aragoto then gets healed by his friendly, neighbourhood Tokusetsu Eisei. He is now conscious, and his bike (automatic equipment) turns back on - and at no point did Aragoto dismount his motorcycle. A model with motorcycle cannot *go* prone, but is it allowed to *be* prone? Does he become a prone S4 or does he instantly pop to his feet/wheels as a standing S4? Additionally, when he fell prone he fell pressed up against a wall. The doctor moved into base contact on the opposite side to the wall. How does the changing silhouette move the Aragoto and the Tokusetsu Eisei, if at all?
Automatic Equipment turning off doesn't mean you dismount, it's a novel concept I haven't heard before, but you need to have the skill active in order to dismount. Additionally, an unconscious biker next to ttheir bike doesn't automatically mount their motorcycle. That would require declaration of the Move short movement skill. Also, the alternative profile is not dependent on the Motorcycle skill being available. The motorcycle doesn't blink in and out of existence as it were.
Yeo. Answered elsewhere. Seemingly the motocycle equipment itself does... nothing? The rules that govern it appear to be more based around the profiles and mount/dismount. Even the fact that a mounted model can't go prone is governed by the prone rules and not the motorcycle rules. So he goes unconscious and stays s4 because he remains mounted.
