Actually it's completely relevant.
Incorrect.
Its relevant because in the video, the guy says that we should feel 1000 mph winds going from side to side, as if we were driving a car at 1000 mph.
In answer to OP, there are so many different versions of FE, that its totally bonkers to try to learn 'em all. Apparently, these guys believe in gravity, which a lot of FErs don't. They don't accept a universal accelerator either, so using this video doesn't really help much for trying to understand FES.
Also, these guys have as much capacity to understand relativity as Skeptimatic. Hilarious.
