shift C / f8 Unrestricted Camera Question

I want to know how to "Freeze" the shift C / f8 unrestricted camera? I see people use it, and place it next to car then it attaches to the car to provide camera angels not possible with the other cameras? How?

 

That is the 'relative' camera, not the shift + C one. In the options menu, under camera, you can enable different cameras and change the order in which the game cycles trhough them

 

Perfect! Thats exactly what I was looking for...for others who may be interested in this discussion, the "Relative Camera" is #5 and use the w,s,a,d keys to reposition the camera...
