I have been thinking lately, and decided it would be really cool if we could have a call out that would be to respond to accidents.
As you arrive on scene, you will see anywhere from 1 to say, 3 cars that have collided in some fashion. You may have injured people in the vehicles, or even injured pedestrians from being hit.
And you also may have witnesses who would be marked with some sort of arrow above their head (like currently the red arrow over wanted persons).
After arriving on scene, your job is to block traffic, call for ambulance/coroner or treat injuries by yourself, and speak to witnesses to gain an understanding of who is at fault and who to ticket.
Then you would give any necessary tickets, tow any vehicles, and clear the scene.
Just thought this would add a lot of realism to the game as currently this is a big thing that cops would be responding to.
