Yeap.Some people are using this a lot.Even in public created lobbies.I wrote it last week and I will do it again..
LOL...When the "most polished AAA PS4 racing title" has a "bug" like that -that affects even e-sports competitive mode- but then we call other titles for having .....game breaking bugs.
I saw it happen last night in a public lobby.So its not fixed entirely.
The "winner" ceremony in the end went to the right guy but the "cheater" was in first position when the results were confirmed.
