Hint: Free Taxi Rides
Here's a great way to get a free taxi fare. Hail a taxi and get inside, and head to your destination. Right before you get to your destination, bust out the back window and point your gun out of the window (using the corresponding controls). Doing so will freak the taxi driver out. He'll stop the car and run away, leaving you near your destination without forcing you to pay for the ride.
