We can map many commands on wheel or button box buttons, even keyboards on PS4.
But for the raceline we need to get out of race and back to menu/options to change it.
Can we please see raceline added to configuration of commands page ?
Just like whipers, pit call, seat adjustment, lap time, hud etc... just be able to see it when we are new to a track we join on the fly and disable it when we feel confident.
i'm sure it would save a few crashes in first curves for guys who did not had time to practice and jump in a race.
