After completing a course, select a different vehicle and play that course again. Now you will be racing against a ghost version of your previous vehicle.
When the last beep is heard as the light is turning green, press Accelerate.
Drive your vehicle (the Backlash works well) right next to an obstacle and press Z. Then, the driver will yell and not exit the vehicle because it is too close to the obstacle. Continue to hold Z until the obstacle explodes. Now use this method to destroy buildings that require demolition by TNT or other non-standard methods. Note: You cannot use this trick on the bonus courses or in the PAL version of the game.
Complete all missions and find all six scientists to unlock two bonus courses. The objective of the first bonus mission is to clear a town of all objects in order to allow a space shuttle to make an emergency landing. The objective of the second bonus mission is to clear all buildings off the Moon. A third bonus mission is accessible only after a perfect score is achieved.
