Useful for controller users, it's instantly improved some of my lap times substantially.
but the actual icon seems to be reaching lock before my car's wheel does. The indicator hits an edge of the circle, then the steering wheel continues to turn for a bit. Not a huge deal, it still makes it way easier to steer on controller.
Small detail, but the ability to change it to a horizontal line instead of a circle would also make this app mandatory for controller users. Kind of similar to how GT7 or GRID on the switch does it.
If those features are added, I'd give it a 5.
