Different Assist Options for Racing Line.

I hope this reaches who it needs to, and I doubt it would be able to be implemented in this years game, but I have quite a few friends who basically depend on the Racing Line assist option, but also don't like how it looks and makes them feel I guess. 

So just like GT:Sport & GT:7, I think there should be options like a cone placed just at the edge of the track instead of 3D or 2D line. So it would only show on their screen, but would be far less obnoxious than the racing line & much better for immersion.

What'd you think?
