Eject Left, Eject Right : This feature causes the specified front seat to engage a quick burst of thrusters located underneath the seat to effectively eject the seat's occupants. On-board computer controls automatically specify the amount of force needed to eject an object to a given height by calculating various variables such as the vehicle's velocity and the object's mass. Note that Eject Left and Eject Right do not automatically engage Auto Roof R or Auto Roof L.
