With AFS IIRC you can over-lay your own lap with that of another racer. Problem is, there is no resource that I am aware of to download a pretty quick time by someone else for comparison.
To date I have only ever been able to watch my own laps with AFS, which is not a great learning tool if you don't get the lines right in the first place.
For those in the know:
1. If you output a MP lap, can you switch between users then overlay your own lap for comparison (I don't think you can)?
2. Is there a resource where *.raf files are available for download (I have checked though a few LFS sites and Googled, with no success)?
If I could compare my laps with someone consistantly better than I (which is not difficult

) then no doubt my times would start to improve.
