Omg , please stop cracking the game and support lfs by buying it! And no you cant modify the track because your not one of the devs , you can only change textures .

No one talked about cracking, it was a question to confirm yes or no.
You do not know how much licenses I purchased for myself and my friends,
might be the biggest LFS supporter

Quote from cargame.nl :

To clarify a bit better.. No, because you are a demo driver. You can use the layout / track editor when you buy a S1 or S2 license.

You mean through clicking on SHIFT+U ? but that does not allow me to
make the road wider or longer rather than creating objects and manipulating
them.
