With this mod, you can use all those carrec paths located in Data/Paths/carrec.img. Use this mod to select the path you want to use via menu.

How to use:
Meanwhile you are using a vehicle, type "CARREC". Select the path you want to use in the menu.
Type "STOP" or exit the vehicle to stop.

Notes:
Don't use trains, it won't work.
Recommended to use an invincibility cheat for the vehicle.
In red, I marked every unused path in the final version of the game.
