In photography (and probably art in general), there's a composition "rule" to frame moving subjects from left to right.
So the direction may not be that interesting!
I wonder if that changes in countries where the main language is written right to left?
Is it culture dependent? Is it because in English we read left to right?
The other thing to consider (as someone who frequently take a photos of their bike) the common direction has the drive side out! In cycling forums it is sacrilegious to post a photo of your bicycle without showing the drive side.
