Start with your fastest character and shift into reverse gear. Reverse all the way until you reach a passenger. Once 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 staying 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.
