B-7: High Speed Driving Lines and Throttle Control
Use the curbs when possible - this makes it so you're not turning as sharply through the corner (a car is faster driving in a straight line than in a corner).
Rule number one of racing is to try and make corners as straight as possible. You accomplish this by running up on curbs, entering corners at a wide angle, and then drifting to the outside of the corner on the exit.
Take the first corner in this test at full speed. Ease up on the throttle for the next two corners and use the curbs.
You may run a little wide on the next corner but it's no big deal because the rest of the track is pretty tame. The main thing is to keep up your momentum for the rest of the run. You will have to tap your brakes slightly for the last corner - Perhaps do this before the corner vs. where the guide tells you to in the middle of it.
Note * Played with a regular six-axis PS3 controller.
