That just changes the driver names, you will need to wait a bit longer for something that can replace textures, models and audio files. I'm hoping for a database editor like f1 2014, that's what I used to use.
And also not changing driver abilities, all that does is replace the names and some pictures, its still technically ie rosberg and not wherlien, I feel it will mess the game up lots, agree in waiting for better mod tools etc, early days in modding
