The crosshairs always point to the player closest to the center of the screen, resulting in a quick and dynamic way to be able to shoot a nearby player immediately. If you want to be able to shoot a specific user, you have to occupy the lock-on, so the sight will not move if another player crosses or moves near the vehicle, that's what the lock-on system is for. You can also keep the crosshairs in manual mode in settings, giving you even more control. This way you have complete control over whom to shoot
