you're wrong in a way i can't comprehend. fully half of that video the camera was pointing at the ground, and the course was way less interesting except for the dog jump section. where are the escalators? B-

Do you mean the super wide angle lens? That’s the norm for action cameras because:

1) you want to capture as much as possible and maybe crop later
2) wide angle acts as a sort of video stabilizer. I’ve got a friend who does steadycam stuff on a DSLR and wide angle makes it way easier to film
3) wide angle also makes it much easier to have a fixed-focus lens which is is the norm for action cameras.
