Drive correctly keeping the proper lane. At the straights it is usually the rightmost, at the turns it depends on where you turn. The turns aren't always limited by barriers (immaginary buses or trucks), but you need to drive over the control points (green circles), so it's better to keep your own lane.
It makes sense to fly around the track in shift+u camera to get familiar with it.
P.S. I've selected the right lane just to do less work (less forbidden zones and barriers).
