Hi,
I'm an LFS newbie, so I don't know if this feature is in the paid version only or not. I would like to use a saved replay as a basis for a new race. It would go like this: do a vanilla single-player race with no opponents, in the next iteration I would race my past me and so on.
Is it possible to do in LFS?
Thanks for any advice

You're looking for a 'ghost lap', which is not currently available, even in paid (licensed) version.
