NOTE: You need lua modloader for this modification

This script comes from an idea by Sauss-Ente described in this forum post https://forum.rvgl.org/viewtopic.php?t=1661
it adds the ability to rotate the car in the frontend after unboxing it in the car selection screen by pressing up and down.

You can also make the rotation slower by holding Left-Ctrl while rotating or faster by holding Left-Shift.
