To successfully pass the mission, get to precinct. To earn a commendation, get to the precinct with 50% or less damage. Chase after the red sports car until you reach the dead end. There are two more enemy cars waiting here for you so get out of there quickly. You'll have to escape back to the police station, but some of the roads will be blocked off. Drive south to get around them. Try to maneuver around objects such as other vehicles, and light poles as you drive through the city. Make it difficult for the perps to get a clear shot at you.
