As a Guy who has raced Motocross I can say from experience: those raised bridges are a perfect double. You can't miss and if you have the right speed you will do no damage.

This Guy blew all his tires out because he had too much speed and over-shot the landing. No big deal, he got his practice lap, he'll get it right next time.

I'd definitely try it on my bike, or someone else's car. There would have to be some money involved..........
