The line comes from German streamer HandOfBlood, known as Hänno, during his police roleplay streams where fans clip his most frantic radio calls. Wagen 8 is his unit call sign and the Carrera shout turned into a running joke in his community because it sounds like an emergency dispatch about a slot car. Clips spread through Twitch highlights, German meme pages and soundboards, and the phrase stayed popular as a shorthand reaction for over-serious police moments and chaotic driving scenes in gaming videos.
