So, what's the high value perspective that leads to penguins always riding bicycles from left to right?
It's actually much less complicated that even that. Consider that there are only two possible sides to show, and one of the sides has the drivetrain on it, whereas the other has basically nothing of importance. It's not much of a choice at all.
Can we have left-chained bicycles, please? (if nothing else, just for the novelty / fun aspect)

Most people if they are to draw a vehicle in motion will draw it moving right. Most (all?) side scroller are rightward. In fact I can't think of a platform side scrolling video game where the primary motion occurs to the left. Most cars advertisement have the car moving right. It makes sense that generative systems would draw motion to the right.
