so i'm leaving the baggage pick up at jfk with my wheeled luggage.
when pushing the bag, noticed that directional stability was better with a lower angle but it was easier to maneuver with a higher angle. (cruiser vs off road?)
when pulling the luggage, increasing the angle made for less directional stability (up to a point) but more maneuverability. while decreasing the angle improved it.
i guess that's how motorcycles work also.
anyway, that's the way my little pea brain works.
