The premise of this awkward sequel to The Cannonball Run is that the father of the rich Arab who lost the Cannonball Run wanted his son to win, so he encourages his son to fund another race, putting up a prize of 1 million (which he expects the son to win back). Both father and son wish to bring glory to their family name, which is Falafel (groan).
The way the Japanese team join the race is pretty awesome. Because the team wanted to avoid a two-day customs quarantine of the computerized car, the car is released from the back of a plane that lands on a road near the airport, deploying and then releasing a parachute to slow it down. The driver ignites the car’s rocket, plunges the car into a lake, and calmly drives the car like a submarine.
