At the entrance of Panau International Airport, get the sports car,
drive it to a runway, and wait for a plane to appear. Go into stunt
position, and attach the car to the plane with the grappling hook. Enter
the car, and the plane will take off with the car in tow. You will
accrue stunt points quickly as long as the grapple is not released.

Drive a fast car or motorcycle on a highway or long road while dodging
traffic in the correct lane. Alternately, drive as fast as possible down
the middle of the road.
