Actually, in this video, its quite obvious, for me at least.
I think you may be focusing on the car, which actually do not look that much different in both 30 & 60fps, which is the only explaination I can think of for you not to notice the difference (if not technical reason that the video cannot play in 60fps). Look ahead of the car, at the trees & environment ahead, & the difference between 30 & 60 is very apparent. 30fps has that stutter effect, more apparent when the car goes a round a corner.
In some videos, it hard to tell 30fps from 60, but this one is quite obvious. But then, I cannot speak for everyone.
