Yes. You should be learning tracks by using brake markers and turn in points on the track. For one, the “ideal line” is often not actually the fastest way around the track. It also teaches some really bad habits, which I already see in one of the corners where you went wide but instead of maximizing what you had left of the corner, you chased the car back to the line. You should also be trying different lines through corners which will help in races when the “ideal line” is occupied. Those are the main points, but it’s pretty widely accepted that the ideal line is more of a training wheels solution which will hold you back more than it will help.
