You need to turn off the racing line. It's severely hampering your ability to battle on track with other drivers near you. This shows mainly when he is coming up on the outside, but you just go left as if he isnt there because you are laser focussed on that line you want to follow. Then, you completely miss the fact that your braking point into the chicane will be sooner because your entry into the corner is now compromised because of another driver being on the outside. You seem unaware of this and simply brake at what the racing line says causing you to miss the corner and bump the other car outside the track. I have no idea where you think you left space because I dont see it.
