For nearly half a century, Mattel’s Hot Wheels toy cars have been allowing people to do what should never be done with full-sized automobiles, namely race them at ridiculous speeds down steep slopes and over ramps at the beach with absolutely no concern for safety whatsoever. That’s just what the demented geniuses of 5 Mad Movie Makers did for their new video, “Hot Wheels Beach Track.” This is the kind of wonderfully meaningless occasion for which adjectives like “awesome” and “epic” are expressly reserved. Other acceptable reactions include “Decent!” and “Nice!” For two glorious minutes, some truly sweet-looking 1:64 vehicles zoom their way down and orange and red plastic track, past various obstacles and even through carefully designed sand tunnels, all amid the sunny climate of palm tree-dotted San Rafael, California. This was probably a son of a bitch to set up, but, man, does it look like fun.
