Looked at the first few minutes of it. I'll watch more later but a couple comments.

1) Hard to be impressed by all CG imagery here; the animator guy can't even decide which way the knees bend on the rears. Perhaps there is more further in that is actual footage of an actual machine in operation.

2) Give me hydrogen power, yes! Make it practical, on a bike or quad, let alone a car, and I'm all for it. I'm rooting for 'em on that score!

3) I want to watch more, but I can see a reality of this sort of thing with legs; nature's all-terrain conveyance. Something like this as a load carrier rather than to be ridden comes to mind.

Hmmmm......
