Big jump in Havana:
In Havana, go to your map. Look for a place that looks like a U shape. It's on the freeway. Go to that place and keep driving East on normal settings. You will get to a green place, pass that. Look to your right, and you will see a little place with a road that goes up to it. Go up the road and turn. Drive to the far wall where there is a clearing of just grass and turn left. HIT THE GAS!!! When you are just about half way over the ledge, get out and press up. Watch your car fly about 20 feet to the ground!

Run down the crowd in Chicago:
Go to Wrigleys Field and get the yellow car. Instead of going out of the gate, turn back around the way you came in. Drive up the slope and face the crowd. If you fly off just right, and you jump out the second your car leaves the slope, your car will fall into the crowd, or coast down the crowd into the field.

Another Havana jump:
I like jumping out of my car on this one, but it works both ways. Go to the place where it says "Ferry" on the map. drive on that road until you see the back of the ferry. Go fast and hit the jump. your car should clear the ferry. Jump out when your car is almost over the ferry, but not quite. you will be standing on the front of the ferry, looking at your car. Your car will fall, and hit the water, but keep going. You can watch your car float there for a long time. Pretty cool.
