NRatings
Author: Mathieu Souphy, currently maintained by ai_line_mod
NRatings is a freeware application, which allows users to semi-automatically update the driver ratings in the .car files. You can use average ratings for the entire season, average ratings of last 3 races on one track or even ratings based on a single race.
Extremely useful for creating realistic rosters. Particularly useful if combined with custom-made driver performance formulas.
