Flip over trucks and buses
Go to the highway in arcade mode and drive on the high lane. Then, knock a truck that says "wow" off the high lane onto the low lane into a truck or bus.
Jack knife trucks
To make 18 wheelers jack knife on the highway, ram them between the cab and the trailer.
Derail train
When in original mode or arcade mode, go to the train station and wait for a train. When one approaches, drive in front of it. The front car of the train will move off the tracks and start honking and try to move. Stay there and eventually the front car will fly off the tracks and will remain that way for a little while.
More money
Your passenger will get excited and give you more money when you pass other drivers on the road.
When taking people on the freeway, weave in and out of buses, trucks, and cars. Your passenger will get excited and give you tips. Be careful not to crash.
Sometimes when you have a customer, you can go against a wall or a solid straight side and ram side by side against it. If done correctly, you can get a Crazy Drift combo even if you did not do one. You can get up to an 8-combo. This works well by KFC with Gus or B.D Joe.
Go to the girl that is waiting at the car store. Pick her up and ride through between the car aisles. She will scream "Yeah!" and cash symbols will begin to surround you car.
Go to the used car shop with a customer and drive through the middle of the two lines of cars to get a lot of tips.
Get to first place
Start the game with your fastest character and shift into reverse gear. Reverse all the way until you reach a passenger. When you have collected her, stay to the center of the road (so that you get more combos for Crazy Through). When you get to the rail car station at the top of the hill, go anyway you want (preferably straight down the middle). Try to stay to the center of the road. Go as fast as you can without crashing into any of the other vehicles. When you get to the bottom of the hill, drop off the passenger. After that, pick up any Red, Orange or (if desired) the Yellow. This will allow you to increase your time, passengers, and money.

Hidden customers

Enable the "Another day mode" code, then begin the game in original mode. There is a hidden customer in the water by the pier.
There is a subway station downtown. Get in by driving down the stairs to find a customer that wants to be taken to another subway station. Just follow the railroad to the next station (the destination may vary) to get some extra cash. Try not to crash, because it will take a lot of time to get back on your way.
A hidden customer is near the parking structure. Drive up the ramp and slowly fall off the end of the structure on the far left side. You will see a green customer on the roof of the building you just landed on. Pick him up. He wants to go 2000 yards and will pay $975 to go to the police station.
Strange customers
Drive down to the beach and into the water in arcade mode. In there are about three or four customers that usually want to go to Pizza Hut. Watch them closely when they hop in and out of the car -- they have unusually big ears.
