Dat friendly viper

I am sick and tired of the cops being around the dang map randomly, please either slow them down or remove them when you not doing missions or nothing, also couple glitches i noticed, 1: when you get out the car sometimes the screen goes dark completely and all i hear is the helicopter, 2: i get stuck on the workout equipment in the new house you added. 3: sometimes when im driving fast and i hit a wall or tree, it launches me in the air so high that it ends up wasting me
