I know what ya mean. I think they are actually a visual thing... attention getter on Youtube and such... Would be a pretty nice machine if it was practical... add a seat and steering and you're all set
I guess it was a fun winter hobby thing. A lot of wasted power. Why not take it further and figure a way to clear the whole drive way at one time. Now that would be impressive! Maybe a chasis with augers in front, left side and right side (sides behind and tucked in slightly from the front one). Also, a heated operators cab.
