A simple script for Multi Theft Auto: San Andreas, which enables players to temporarily disable their vehicle collisions to pass through other vehicles, objects and so on.
To use the script, hold 'x' on the keyboard while driving a vehicle. That's all! The main use is to play around in freeroam. Perhaps it would be also useful while making maps.
The biggest problem with turning all vehicle collisions off is that it moves upwards all the time, so to avoid that, the vehicle's velocity in Z direction is saved while activating ghost and applied for all of its duration. It makes it behave unexpectedly sometimes, but may be used as a feature.
