Briggs LO206 Senior Final from the 2017 GoPro Motorplex Karting Challenge, listed as round 1 in the original title and round 12 in the original writeup. The driver left the course early after thinking marshals were flagging that kart off, when they were actually signaling the kart immediately behind because its rear bumper was dragging. From that view it looked like the flags were for this kart. Sorry to Justin Mann for the spin in turn 8.
