Racing line, braking point option

Learning the Track/Braking Points can be done in about 10 laps of Time Trial. It's not time consuming. Here's a handy way to do it. Set the fastest lap you can on Time Trial with the racing line on, then switch it off and follow what your ghost car is doing. You'll start to notice different reference points for where you need to brake because you're no longer staring at the track surface looking for a red line to appear.
