Most of the Golds are fairly easy to get, except for one: Scene 24. You've got to drive towards the camera and finish 75m ahead of Hammond. It is quite frankly horrendous. The map is opposite, the controls are opposite.. its not easy.
Until you figure out the easy way: don't watch what you're doing. No, I'm not joking and I have not lost the plot.
Ignore what's going on on screen and focus entirely on the roadmap in the bottom left corner. You steer left, you go left. Focus on the map and try and keep the top point of the arrow marker in the center of the white line. If you can keep that arrow dead centre, steering left and right as the map bends left and right... it makes it a doddle. I finished 184m ahead of Hammond.
The rest of the Golds should be a breeze! Good luck!
