LOL. The video basically demonstrates that relative velocity works exactly as "globetards" say it does. Note that while on the truck, definitely do not hang your arm or leg over the side and hit a sign passing by, as it will be moving 80 km/hr. Also note that while getting launched down the bed of the truck, definitely do not hang and arm or leg over the side and hit anything attached to the truck, as it will be moving 80 km/hr.
But, if you do the experiment correctly, you land on the street as planned. Also, just to be a stickler, the video is entitled "He Trusted Physics..." but this is not quite right. Only some fool would not trust "physics" when it is a concept as simple as relative velocity. What this guy actually trusted, and this is much less certain and scarier, is engineering. If the sled launching system had a 10% error, the guy would have had to land at 8 km/hr, which is 5 mi/hr. Every additional 10% on the error would be another 5 mi/hr when hitting the pavement.
