For many decades, it was the standard and our brains have gotten very used with it. But now, when basically any phone can shoot 60+ pfs, when we watch the videos, then we see 60 frames every second and our brain senses this motion as incredibly fluid and smooth, which is why videos in 60fps look so weird and surreal, especially when we see fast moving objects like rally cars. This is actually the same reason why movies are still in 24 fps. Studios probably record movies 4k 120 pfs, but what we see in the cinema is 24 fps as anything higher feels unnatural and bizarre for us. So to sum up... it's the brain.
