Kids and kids at heart love Legos, especially motorized Legos. It's fun to dream up challenges and engineer solutions to eliminate obstacles. Or watch from the sidelines while someone builds something clever. That's why Lego videos on YouTube are fun to watch.
This video is titled "Driving Lego Cars in the Sand" and was put together by Brick Technology, who also did one on parallel parking and another where they built a hot rod with a working clutch and four-speed gearbox. They have a number of videos on their YouTube channel, which is like a cross between Engineering Explained and Lego Movie 2.
