You know, not just anyone can show up with a stack of video cameras to an American Le Mans race expecting to be allowed to shoot footage. If you are a professional photographer, then you might be allowed trackside access to shoot photos, but permission to shoot video is a whole other matter and often requires several weeks of negotiations.
On top of this, not just anyone would be able to convince BMW to mount video cameras all over brand new race car — and even onto the driver!
The video you see here exists in part due to the strong relationship between Need for Speed and BMW.
