Let’s get the preliminaries out of the way. There’s another video of Dirt Showdown doing the rounds, this one avoiding the collisions and boosting that have been the highlights of previous trailers, and instead seeming to show a mating ritual between automobiles. Perhaps some form of dance. I don’t know, but it’s not as much fun as the actual grinding of metal on metal, the eruption of oil and petrol, the concertina crunch of repeated impact. You can see the coquettish conveyances below and you can also bear witness to only the second time I’ve been amused by an achievement.
