There's a reason, of course, why the wingwalker is not automatically accelerated to always match the pushback speed, and it's precisely not obtaining funny nicknames!
If we just accelerate it, it might look less "Priscilla", and more "Charlie Chaplin", like the common effect of the old movies filmed at 18 fps and played back at the current 24 fps cinema standard.
So yes, we might do something about it, but we'll probably have to remodeling him to use a more decide pace. Which is not the same thing as playing him faster...that's clearly something to do for the next big GSX update, the Pushback remake.
