There was a youtuber who had an old bulldozer in a farm and someone suggested he rolled it up and down a steep hill he had on his land. He did so but he made the mistake of leaving it in gear while rolling down with the clutch in and once he made it at the bottom he realized that the clutch had exploded. The bulldozer must have never reached a speed higher than 10 mph while going downhill but thanks to the insane gear ratio it still spun the clutch disk so fast that it tore itself apart with the centrifugal forces.
I just thought it was an interesting story telling how not made to go fast these things are.
