No tyre wear in New Zeland...tested R5 Skoda in weekly Challenge and A-group Mitsubishi in career. I can drive the whole rally with the same soft tires and the tires don't wear at all.
Why didn't you add a editor to record your own notes? It would also be easy to implement for consoles. Everyone should be able to record notes in their own language and also add a feature to share and download notes from other players.
