Quote from Stefani24 :While on track press shift+o then go to the view tab. Tadaa :bananadea at you Stefani. He means the camera hack where u can cruise with view trough all the track as far and as high as you want. For as far as I know there is not one for Z, maybe try using older versions.
Or just use TV Director and set a camera to like 500m, in fact if you set the nodes to cover the full track you can watch a race from above
