Bail Out

A bailout refers to the 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 it is in a complete stop.

Description
Bailouts are often used as a quick escape maneuvuer from vehicles when a vehicle is either in danger of exploding, entering dangerous grounds, or about to fall off a cliff or into water. Bailouts are executed by using the same key or button that the player uses to enter or exit vehicles whilst the vehicle is still travelling at a minimum of 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

Bailouts can be done from moving land vehicles, including motorbikes and bicycles, as well as aircraft. As falls from high altitudes can be lethal in GTA San Andreas, players are equipped with parachutes upon entry into any aircraft to ensure the player has a chance of survival after ejection.
