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).
[edit] updated the track

BTW, now it offers another challenge: try stopping at each traffic light and crossover and save your clutch from overheating.
I wanna have [TC] City Driving UK NOW! =[ i miss it from a year ago. It was the best layout and the best server ever made. Extremely fun and tricky...
