He spends much of the time arresting criminals, taking people to the hospital in an ambulance, and putting out fires.
At this point my son was familiar with the game's mechanics and hopped into the ambulance. As he put the crime fighting behind him, he wondered aloud if it was possible to take people to the hospital. I instruct him to press R3, and then he was off to save a few lives. He was having a blast racing from point to point, picking up people in need, and then speeding off to Las Venturas Hospital. During one of his life saving adventures, he passed a fire house with a big, red, shiny fire truck parked out front. He didn't want to let his passengers down, so he took them to the hospital and then asked if I could guide him back to the fire truck.
