Time to explore the streets of Berlin! Is there a better way to do this than as a cab driver? Take your passengers to their destinations and collect points to earn as much money as possible. Transport your passengers quickly and safely, because the fare diminishes if the trip lasts too long, or if you bump into other cars and buildings. Don't forget to refuel at the fuel station, or else your car will break down. And most of all: steer clear from the police! Good luck!
