When I first saw this I had to double-take. Reddit is fond of editing the upvote symbol into GIFs, but this video is the real deal. The Dogecoin NASCAR, driven by Josh Wise, uses upvote flags to signal where the pit stop is.
It's this level of detail that makes the Dogecoin NASCAR sponsorship so great. We really need to see the #98 car with Doge on it all next season. Internets, raise the money!
