There's no such thing as an algorithm, the 1-2-3 exploit is bullshit as well. So yeah, the pink slips are RNG. If you want further proof, I can tell you How I got the first 4 cars: Sonny: 2nd marker Taz: 2nd marker Vic: 1st marker Izzy: 3rd marker. Just to show you that the 1-2-3 exploit doesn't work.
