Drax0r - It's three 3in suction cups on a metal plate. You attach it with the camera on a 1ft extension, add a fish-eye lens and get your mate to drive around at 3mph with the shutter speed at 10+ secs (which is why the light-lines are wobbley
)
I've tested a Single 5in suction mount at over 90mph (with a video camera) so this 9in (effectively) mount is very safe. I still need to test it on the track really to be certain - gonna bodge a 3kg box to attach for testing in case it does fail so I don't damage anything. However, on a long extension you get camera wobble - it really needs another point of contact on the car to stop that.
