Yes mechanic is allowed just not the super nitro thing

Yes you can use unlimited credits/ gas

I don’t think y’all are all fully optimized bc on several runs I’ve done rounds 2,3 or 4 in like 10 seconds but never in the same run so I think a sub 3 maybe even a sub 2:20 would be possible just got back into speed running zombies maps and stuff there will be more of me just idk
