Hi, I saw Stunts listed as possible future project by the legendary taser eien86. So I made a thread for it and listed all the tricks that I know. (I am not tasing this game myself.)

Super speed and spontaneous flight:

In some version of Stunts (or all versions) you can slowly bump against the opponent car to zip very fast. The result is unpredictable and gives the car insane speed in seemingly random directions, usually backwards. The car is often lifted off the ground, but sometimes can traverse horizontally. Usually the result is a very high flight and a crashlanding. With precise adjustment you can get lower angle and even survive the fall (smoothly against a mountain slope for example), but surviving is rare, I've seen it maybe once or twice after hundreds of zips. The probability of surviving the fast zip could be something like 1%.
Another trick is that a very fast car (the F1 car) can lift off the ground spontaneously making a very long jump.
Sometimes you can turn upside down and survive, now the car is driving upside down. The easiest way to set it up is by driving upside down in a tunnel.
The cars have different properties, so some tricks may only work on specific cars. I know that the jeep (1986 Lamborghini LM002) can climb walls without being destroyed. Maybe some other cars can climb walls also, but it seems harder to do. The jeep feels more durable and has slow acceleration making it easier to survive the vertical wall climb.
What category to TAS?
Completing the default track as fast as possible is the basic racing category. It can be interesting! It probably involves bumping the opponent car to gain super speed and then fly most of the track in a few seconds. Difficult detail to solve is: Which car should the opponent use? Very probably the player car is the F1 because it is the fastest car, but there is a small chance that some other car can make faster and more survivable fast zip, but I do not believe that to be the case.
If we give jeep to the opponent then we have more precise control of opponent speed, because jeep accelerates slowly. This is why I think the opponent should use jeep, but I may be wrong about it.
A playaround run would be a great category for Stunts. That would involve making your own track that uses all possible game mechanics and then using the F1 car to perform as many different trick jumps as possible.
The most important trick when building the track: You can make the track as a simple loop. Then the game checks the track to see that it is a valid loop. Now you can put anything in the remaining portion of the map and the game will see it as a valid track. Now you can build ridiculous obstacle combinations that are not allowed normally.
A simplified list of known tricks for a playaround run:
* build the track so that you can immediately bump into the opponent car to make the opponent fly in a funny way against some complex obstacles
* drive up a vertical wall (adjust speed and angle to survive)
* drive the same corkscrew/loop multiple times
* gain super speed with the F1 car and lift off the ground spontaneously
* paradoxical jump: hit a down ramp with a correct angle to gain upwards momentum instead, then survive the fall
* various jump tricks: jump into various obstacles for all kinds of strange results
* use a tunnel ceiling to turn upside down and then finish the race driving upside down (this should be the final trick if you can't find a way to flip the car upside up again... the car is easily destroyed when driving upside down, it can spontaneously combust...)
