Mafia

Break into a car during story mode to unlock it in Free Ride mode.

When you first start driving, go all the way down the road and take a right. Follow this road. This will lead you to where there is only a right turn. Take the turn. Looking left, there seems to be a small barrier blocking the ocean. At the beginning of the turn there is actually a hidden bottom where you can drive. If you slow down to about 50 or 60 miles per hour, drive over the barrier. By going slow enough, you can land at the bottom drive part. The enemy gangsters will not slow down. They will follow you over the barrier. If they have the correct angle or speed, they will fly into the ocean or land upside down. If you have not gone over the ocean or flipped over, there is a ramp where you can escape the gangsters and finish the level. Note: This may require a few attempts.

Win first place in all races in racing championship mode.

As soon as you enter free ride mode, you will start in a car with a reddish gate directly behind you. Drive forward so that you are in the street, then reverse right back to the location you started. A car selection screen will appear, and you can select any unlocked car.

Kill the men in the all black suits with the black hat (gangsters) to earn $500 each. Go into the country and speed in a fast car. Blow up cars for $100 each. Drive taxis to earn money.

When you’re in the city and your car has crashed a number of times, you can return to where you started next to Salieri's Bar and choose any car. Then, just move forward onto the street and reverse back towards the gate and choose your first car. It will be back to normal with all its doors, windows, etc.

Walk behind them and shoot them. This works best with the sawed off shotgun.

Get inside of a trolley, a rail station, or an elevated rail station and wait until your wanted level subsides.

To clear up the roads ahead of you, you can make traffic vanish by simply looking in your rear-view mirror--hold DOWN on the right analog stick. This works best with cars at a distance and on the connecting bridges and tunnels.
