Suspect Rival times

was just doing a Rival challenge,it was the Mazda MX-5 Gen 1 (D class 329) restircted,at Indy. After doing around 20 laps and setting my best lap I noticed I was 51 secs short of the top time.
How is that possible I thought,so I checked the leaderboards and the top time was done in a A class Nissan GTR.
Did this guy hack the game somehow? How is it possible? I’ve always thought that some of the times on Rivals are a bit suspect but just wrote it off as “They’re really good”,now I’m not so sure.

I believe it is a glitch in the database and nothing to do with what the player did.

thought it might be that aswell,I didn’t report the player for this reason.
