While driving the at the Silverstone track , about halfway to the end of the track, you will notice several grandstands on the left side of the road. After the third or fourth in a row on the left, a hotel will come into view. If you continue towards the hotel, and don't make the turn, you will see a service road. Continue on that road, and it will lead you back onto the main track. You will advance several positions in the race if you do this correctly.
