Pursuer never speeds past if they're any good. As a pursuer, I know this. All slowing down and turning usually does is give them a big, slow, full-profile target to shoot. If chase cam is disabled, you can pull a hard turn and then pull another hard turn in the opposite direction when you're out of their FOV so they're not prepared to follow. My strategy is to afterburner at max speed hugging the ground into the out of bounds area, then do a 180 trying to time my reentry with about 3 seconds left. This causes your pursuer's screen to go into black and white bloom with a big suicide countdown timer in the center, which throws off their vision and often scares them off the pursuit because they don't know if I'm actually going to lead them to into suicide or not.
