As the title says, I managed to break out of the track. I sound a bit weird and muffled here, but anyway here's the footage filmed with my hopelessly shaky hand.
09 No chicane... Go to the tyre wall at the end of the first long straight and park in the centre of the median lines. Have someone hit you through in your X1 or other small/light car with a Tank Car or Veyron. You can also go 380km/hr odd and pull the handbrake at the start of the median and hit the wall really flat with the right side of your car and drive through. Doing the handbrake method, use the heaviest car you can, although the stock weight veyron works best.
