A lot of people seem to be misreading the OP, I'm not saying anyone is confusing this particular Starlink racing footage for Starfox GP.
I'm saying it's possible that whoever started this Starfox GP rumor saw various bits of development footage of Starlink with Starfox in the footage. And possibly one of the first pieces of footage they saw was this racing mode, followed by other footage from the rest of the game.
The rest of the game includes space flight, combat, boss battles, missions, a hub, cutscenes with characters interacting, basically everything that has been rumored to be in Starfox GP. If someone got this leaked footage and the first thing they saw was this racing mode and then afterwards saw all of the other stuff, it's possible they mistook the entire game for a racing game that includes all of those other elements.
Ubisoft works on DLC years in advance of when it launches so racing DLC footage being leaked isn't that far fetched.
