For how I personally feel about Tails' taunts towards Rouge and Shadow in Team Sonic Racing, as much as out of character they are, I'm fine with them seeing that it's at least a step up from his portrayals in recent years because he actually sounds confident. This is also meant to be a competitive racing game, plus a spin-off, so them trying to be as accurate as possible isn't really a high priority, and even Nintendo do the same with their spin-off games, like in Mario kart 8 you have Luigi's death stare despite him not really being a character to do such a thing.
