100% me and my thoughts alone in my head cooking up a storm. Also some more limitations: The way it is detected is by using actual circles, not points (which have 0 area, and thus are the most accurate) which makes the game have a slight error margin. At higher speeds it doesn't really work and it needs a "Collision Sweet Spot" (to counteract going forward) of greater than 1 to work.
