Something seems off about this video. I just can’t put my finger on it. He’s got the speed down. The wheels seem to be spinning in the correct direction. The rain doesn’t seem to be affecting him, so that can’t be it. He starts mowing the grass about halfway through, but it’s likely that he needs a side gig and does landscaping in his off hours.
I’ve got it! He keeps making right turns. What a weirdo. Everyone knows racetracks only have left turns.
