Right now, the Spillway Climb record is 07.552 using the suggested SBR4 Hillclimb-Asphalt (DCT) however I figured out that using other vehicles (which is allowed by the rules, but may be against the spirit of the run) can be faster. I ran with the Moonhawk Drag for like 10 minutes and got a 07.43, I think we can get this "Spillway Climb - Any Vehicle" category a lot lower than "Spillway Climb - Default Car" and I think we should split it and any other (non-time trial) scenario with multiple vehicles available into "Default Car" and "Any Vehicle" Categories.

07.43 Moonhawk run -

I think if we start doing this 'Any vehicle' and 'default vehicle', we would start having alot more categories for each scenario since people would drive other vehicles instead of the stock vehicle.

It is a great idea and all, but it might be a slight inconvenience to the moderators to make more and more sub-categories to the scenarios.

the endless category spiral, a mainstay of speedrunning

I think this would be a good category split. To my knowledge there's only a couple scenarios right now that you can even use other cars in while set to competitive scenario conditions. It wouldn't be difficult to do.
