@itchboyI hope you are aware of the game crashing issue for when you go to shoot a car as a cop. When you draw your weapon, and hover your mouse over a car, it will show handcuffs, as you cannot arrest a car. When you click, the game freezes and crashes. If you catch your mistake, manually clicking the shoot command will fix it for that moment.
Large trucks get stuck on the tight corners and often do not move even if the traffic lights are green. Therefore you have to shoot them and tow the trucks. This is rather irritating when it comes to quick responses.
