a mod for racing line

Autosave setting is doing basically the same, without forcing you to save. Autosave is only available once you joined and left a track. Actually it is just the name of the autosave.rrbin file which is created first time you entered track.
When you play in rain your autosave rubber is gone however...

I don't use autosave because I make multiple saves depending on the condition then choose one of them. Sometimes the rubber marks become too much.
