Driving off a cliff is never as easy as it sounds. There are guard-rails. Those are designed to not admit cars. There's a shoulder, to give an extra second of reaction time. There's an angle to be overcome; the car can't just slide along and hope to burst through. Once conditions are perfect, the car might not even go sailing over the edge. Once the speed and angle are perfect and the brake is forgotten in favor of the gas, the shards of metal railing might slow your descent enough that your car merely scrapes slowly over the edge so that it can roll violently down the cliff, instead of sailing through the air--perfect, weightless, slow-motion--until it crushes itself against the bottom with extra-violent force.

Once you've driven over, though, you just have to enjoy that you've done something fairly difficult and you've done it so well. Sit back and enjoy the spectacle. Hope that nothing particularly painful happens at the bottom. Hope that perhaps, if you're very lucky, your car will survive and you can race up the mountain and through the hole you just punched in the guard-rail.
