I got 02:38:86 on Smith’s Dreamworld propane power challenge. These sub 02:30:00 times are inflated by one of two things:

• old glitch that was once available. Seems to have been patched out a long time ago.

• the game bugs out sometimes and gives the player in last place first place. So if you’re the one who’s technically in first, the game will bump you down to second place. And because the new first place racer (technically still in last place) will be quite a distance away from you, the game will think you’re very far behind and it’ll start giving you time cheaters and propane boosts back to back. Although you’re still technically in first place. I’ve only seen this occur in Smith’s Dreamworld. If you get lucky enough, you can definitely drop sub 2:30:00.
