There was also the Top Gear challenge where they purchased 4wd cars in Bolivia, and were dropped off in the jungle.
James May is terrified of heights, and as they're starting out tells Jeremy and Richard that if they play their old joke of running ino the back of his car, he'll cut their "bleeping heads off..." Richard does eventually slamw into the back of May, May stops his car, pulls out his machete, and proceeds to poke it through the window of Hammonds FJ40.At one point, the alternator in James Mays Suzuki Samurai dies. To make matter worse, they are in the dark near the start of the Bolivian "Death Road." It's getting dark, and they still have to drive the rest of the way. Hammond and May switch batteries so that James can continue to drive, but, because the alternator isn't charging the battery, May can't use his headlights. They solve the problem by taping two or three of those 9LED 3AAA lights on his bumper, and he follows Hammonds FJ40 at about 10feet.
