Anyone else ride around and realize the NPC's are just too law abiding. Even gangs like the Ballas never really commit crimes and only ever pull a gun on your if you have first.
I think it would be great if you saw NPC's acting like we do, killing other NPC's or robbing a store or better still attempting to commit crimes against us. Imagine minding your own business then on the radar you see a red blip or blips to indicate that trouble is heading your way.
You could even have it like Red Dead where you help the store keepers out when they've been robbed, but only if you're in the vicinity (having an alert about a store being robbed miles away would be unrealistic).
I know we can have muggers sent after us but that very very rarely happens.
There should be more criminals in Los Santos free roam than just us humans.
