I don’t think light is as fast as it claims to be. Maybe off the line and all laps on modern tracks, but there’s no way light can keep that speed up. Light has to get tired out eventually and I don’t think its particularly aerodynamic. Have you seen wind tunnel testing? The lighting is atrocious! Anyways, how fast can light be when darkness is setting the same drag times in REVERSE?! Don’t even bother looking up times online since light is a proud sponsor of every publication, like Porsche.
