Shooting this video is indeed a high unification of courage and technology! This is indisputable! However, it must be said that this kind of inward-arch outward-concave imaging lens does exaggerate the steepness on both sides of the riding path and the arch in the middle. In reality, it's absolutely not as dangerous as it looks in the video - only 40% of the perceived danger is real.
