I'm pretty sure rocket racing car speed has been decreased by around 3.25% Idk what will happen if this dosent get reverted it results times to be around 3-4s slower than old speed

I think that we have to wait for an update of the game and until then if the speed is not fixed like it was before then the old wr's go to a separate category or something like that.

Correct. Although there is a WR I'm aware of that was driven with the new speed on Anaconda... it's kinda nuts too
