Thrashin' RC in 1 second

Alright, how do I even explain this? I guess, I'll have to divide it into 2 parts: how it works and why it works.

For the "how it works" part just watch the VOD. Some notes: all vehicles are marked. Stinger is AP/PP. You can get BP/FP/EP from Car Salesman and apply PP and DP conversions. Also, there are some easier illegal methods of getting a Rhino, but if you're using them, you suck :)

Now "why it works". First of all, there are 2 ways of passing RC races in this game - finish first or collect any checkpoint while all of your opponents are dead. We, obviously, want to abuse the latter. RC opponents have a lot of properties during the race, so I don't know if there's any way of destroying them. The only idea I had was using a Rhino. But for that we need to make it RC. I'm sure there're a lot of other, better missions for that "conversion", but currently the only known one is Driving Mr Leone.

To unlock the 6 stars wanted level you simply start AWOL Angel. Also, keep in mind that getting the second Rhino during the mission is mandatory. If you don't have it, then the game will crash. If you get 2 before the mission, then 1 disappears. I'm not sure why. As for the crash, I think it's related to unloading the model. Bumps and Grinds doesn't just teleport your vehicle. It destroys it and creates a new one of the same model. Looks like the model is unloaded during that process.

Reentering Manchez is also mandatory. If you don't do it, the game will crash when you get far away from it. No idea why that happens - in reLCS it doesn't.

Why does your vehicle become RC? Well, WARP_PLAYER_INTO_CAR doesn't check if you're in a vehicle or not, so if you're then that vehicle still has STATUS_PLAYER (thanks @Nick007J).

If you wonder why it takes so long for the second Bumps and Grinds instance to appear, then it's easy to explain. The Course 10 mission script is quite short compared to Driving Mr Leone's one, so when the dupe happens you have "2 missions in 1" - the start is an entirety of Course 10 script and the rest is leftovers from Driving Mr Leone. The last cutscenes section is located at high offsets (that are not overwritten), so we get to B&G only after the return from GOSUB.

I think that's everything you need to know. If something is still unclear, feel free to ping me in the speedrunning Discord server.
