Those are identical descriptions to an aircraft (well, maybe not the 'keel' bit 😏 Car designers also have targets for these on test circuits, especially yaw when heavy breaking. I wonder if a car has the same secondary effects as a fixed wing aircraft? Secondary effect of yaw is roll and vica-versa. |
