If you get bored with the game I found a way to turn it into a demolition derby and not get any penalties.
Find a place where the wall is near the track, get along side a car so that their front wheels are at your side pods and just drive them into the wall. You get away with no damage (unless they spin you and you hit the wall lol) and you don't get a penalty.
Now it's time to try for a HRT 1-2 finish haha
And no, I didn't try this on purpose. I had to move over to avoid smashing into a spun car and didn't know Sutil was beside me. And yes, I have done it since then to keep the race entertaining.
