If on occasion, a cop on foot, or on a squad car comes near, the hooker will get out of the car and run as if scared, and the player will get a one-star wanted level.
It is possible to lengthen the service by driving a short distance while the car is shaking, then the speed of the shaking will reset to the slowest and the player will get more health.
By entering cheats, it is possible for multiple hookers to enter the player's vehicle, and if the service is finished, only the last hooker will get out, and the other hookers will remain until the player gets out, then all the hookers will also exit the vehicle.
This was taken off in the PC version, but can be re-enabled using mods.
Since seclusion is now considered, when the car shakes at its fastest and anyone which is not a hooker comes near the car, the hooker will stop the service immediately and get out of the car.
Different prostitutes with different voices and personalities are featured, including possibly a "Crying Game" scenario; normally after sex, Carl makes some sort of comment about the experience as the girl exits his vehicle - but sometimes a different male voice can be heard, which could indicate that Carl's "date" wasn't female, though this could just be a glitch.
