This tool assisted speedrun (TAS) was made using a cheatcode that makes it possible to drive with a speed up to 200 km/h, this time will not count on any real rankings, it's just for entertainment purpose.
A tool-assisted speedrun or tool-assisted superplay (TAS) is generally defined as speedrunning a game in an emulator with the goal of creating a theoretically perfect playthrough. The TAS author would use their knowledge of the game's mechanics and various tools built into the emulator to optimize a speedrun until no more improvements can be identified. Tools used to this end include using savestates and branches, slow-down and going frame-by-frame. - Wikipedia https://en.wikipedia.org/wiki/Tool-assisted_speedrun
