My original inspiration for creating Slingshot Speeders was a bug in Kerbal Space Program 2 from over three years ago

The "Kraken Drive" was a bug that let you break the physics by placing a cube on top of a Rapier engine creating an opposite reaction force much higher than the original force (I was not the original one who found the bug). I exploited it and did the fastest speed run to the moon and back, I think I'm the only one who did this which is kind of funny. The ability to break the physics and the fun I had made me think of how cool it would be to create a racing game where this kind of gameplay was actually encouraged.
