Just a quick clarification, if we are pushed into cutting because we didn't have any space and we let the other one by if we gain an advantage, do we still get a penalty?
I did it in LFSBC season 2 (was just joining the race for fun ) and it really depends of the corner. In this case it was the turn before the final chicane in AS5. You just need to carry more speed through the corner. What I did was brake slightly later then him, squeeze a little to make sure I get as close as possible from the apex and get on the throttle slightly before him since I'm a little wider and get to carry more speed (the corner is tilted a little towards the inside.)
He doesn't like the new name you're giving him I guess, he's just running away. Try a different name maybe he'll like it more and actually stay in the car.
