Bail Out

A bail out refers to an act of jumping from a moving vehicle. The ability is first used in Grand Theft Auto: Vice City, and has since been adopted in most Grand Theft Auto games after. Until GTA Vice City, the player can only exit vehicles once they come to a complete stop (with the exception of ships).

Description
Bail outs are often used as a quick escape maneuver from a vehicle when the vehicle is either in danger of exploding, entering dangerous grounds, or about to fall off a cliff or into water. Bail outs are executed by using the same key or button that the player uses to enter or exit vehicles, whilst the vehicle is still traveling at minimally average speed. In most cases, the player will lose a small amount of health as a result of the hitting the ground after exiting the vehicle; in Grand Theft Auto IV, the use of ragdoll physics makes it hard to predict the amount of damage the player will take after exiting a moving vehicle, but in Grand Theft Auto: San Andreas, the player will not lose health when bailing out.

Bail outs can be done from moving land vehicles, including motorbikes and bicycles, as well as aircraft. However bailing out from cars in mid air is impossible for some reason. As falls from high altitudes can be lethal in GTA San Andreas, players are equipped with parachutes after exiting any aircraft at a height to ensure the player has a chance of survival after ejecting.
