First of all I would like to say Tesla seems like a great guy; I think there was a bug in one of the races on this map where his car didn't change from plane mode to the other modes (car/boat).
I have attached a short clip of it: https://streamable.com/s293q
Here's a screenshot at the end of the race (I am sure 5:10 is possible; but if Tesla didn't die, he would have gotten 4:30)
I am not accusing him of cheating, nope, I just think there was a server/client bug during that race that caused it.
