No it wouldnt work i tried a stunt like this ages ago wen i was a bit mad lol i found a huge hill and made 2 dirt jumps 45 ft apart then i did it on a mountain board landed perfect then hit a tree and bruised all my ribs and my jaw it was a bit stupid Also i spotted a huge downhill country road with like 25% hills , so i took the challenge.. i built a go cart out of wood , had custom steel axels made , you turn with your feet and screwed a plastic bit off a school chair to it , put wheelbaro wheels on it and raced it down with about 50 psi over the max in each tyre i went down , i was accelerating way too much and i had noo brakes and just a dh helmet on , i was overtaking cars slowing down for the hills the as i was hitting the last hill i got down ( my eyes were watering and i was getting speed shakes and wiggles ) Then i noticed hay above a bush ( ahhh ) i hit a blind corner as if it was a track hit a pebble and flipped over ( slided on my head for 50+ft went throught a fence into a garden..
