This is very cool, but what mechanism lets me see the roof of the cars on the big wheel?

The cars seem to twist towards me as they approach and away from me as they recede, but from my initial stationary position, which is below the roof of the lowest car, I feel that I shouldn’t ever be able to see light from the top surface of a car’s roof?

If I toggle ‘L’ off then indeed, I can’t see the top of any of those cars. But I feel that even with it on, and in the absence of gravitational lensing, I feel the path of light from that top surface would always be blocked?
