The kid/little man is a time traveler who is ahead in the game. Like revealed in the cartoon Midnight Gospel by secret sages that hide secrets in media, when you overcome suffering you are gifted and trusted with the ability to navigate time like a video.
He is playing with this world/time and wanted to experience the perfect boost, because why not, among other things he already have done: tasted all food, committed all crimes, played with all toys and operated all machines, you become vulnerable to boredom. He knew where the accident would have happened, he checked if no one was looking and did it.
After having exhausted his libido doing things that trigger the lowest senses, the next experience in line in the pyramid of existence is exploring space and the laws of physics, like he did in the video, then read all books and talk to all sages and ultimately reach godhood.

"the Syntonic Lodge is another name for the dark brotherhood manipulating history not like an ooga booga conspiracy but as a group of individuals who can read the writing on the wall when it comes to the inherent, Malthusian dynamics of complex systems and then mobilize to put themselves in a position to reap its fruits..."
That was told by a prophet.

We might have just watched one of "them"!
Holy shit dude...
