Couldn't do that in Oz, rec droners aren't allowed to fly after dark......what I want to know is how does the rider know where he is going in the dark? He's not doing that from memory.....
Watch the behind the scenes video, he states he is familiar with the track. And Yes, it was shot incrementally, giving the impression of a one time through effect. Very well done..... I want those cameras (Throws a fit)....
