As a sane rational human being, I can see that attaching a treadmill to a car and attempting to surf on it is never going to work. Obviously this guy doesn’t have that sort of foresight.
To be fair, this looks like a lot of fun. But of course, it’s never going to last. And that’s exactly why we’re watching him doing it instead of grabbing our own treadmill and giving it a try.
The ending is predictable, but no less satisfying. It may not be nice to laugh at the misfortunes of others, but when the victim is this stupid I think it’s justified.
