This is a port of the "Jump Board" mod by #Eugeniusz, ported by GTASAFAN. "JUMPB" activation has been changed to 2+8.
Slightly edited description from the author of the script:
This mod adds the ability to create a trampoline in front of your character's car, which, in turn, can clear the way for you from other cars. Yes, more than once we noticed that on the slopes of San Andreas it is quite dense traffic and often there are accidents. The same mod can make it easier for you to move around due to the fact that with the help of this simple trampoline, you will easily rush along the track, without fear of collision.
Instruction:
Download the archive with the mod, unzip the file "CarBoard.csa" and copy/move it along the path Android/data/com.rockstargames.gtasa (not in files).
Activating and using the mod: After installing the file necessary for work, start the game. Get into the car (it will not work with air and water transport), then click on the "2+8" zones
