Pavement Skiing
Contestants drop off the of a vehicle going very fast and try to stay on their feet. | |
DON"T DO THIS!
There's a variation of the thing we did as a kid called
ghostriding where instead of the bikes we jumped off of
while they were moving, they jump out of cars that are
moving.
This is a "sport" for the stupidest of the stupid and I don't
condone it at all. However, a variation
of this where you
leave somebody behind the wheel and have a
participant,
properly trussed up in protective gear, dismount from the
back of a vehicle going 50, 80, 100 mph or more to try to
stay on his feet and slide as far as possible might be a
balance of danger and entertainment that I could get
behind.
That being said I'm not sure if there's a combination of
helmet, elbow and knee pads, back braces etc that could
protect somebody loosing their balance while they slide
along the pavement at 120 miles per hour.
One way to find out I guess.
Sort of...

People hang on to the back of their motorbike with titanium (I think) on their boot-heels. [neutrinos_shadow, Jun 05 2019]

If it's a reasonably flat road, you really only have to worry
about friction. You want something which: |
|
| |
(a) doesn't have too low friction, or you'll skid a long
way
(b) doesn't have too high friction, or you'll roll instead of
skidding
(c) can absorb your kinetic energy without wearing
through
(d) through ablation or insulation, doesn't transmit all that
energy as heat to your skin. |
|
| |
An 80kg person travelling at 120mph needs to dump about
120kJ of kinetic energy. That's a trivial amount of energy. |
|
| |
(e) And sparks. The protective boots should throw lots
and
lots
of sparks. |
|
| |
I suppose if you wanted to be a sick cookie you could
have
the protective areas of the suit, knee pads, helmet etc.
throw sparks as well just in case. |

Hey, if you've gotta wipe out, might as well make a show
of it. Let's face it, anybody who would pay to see such an
event wouldn't exactly ask for their money back if there
were a disaster. |

It was a stupid thing to do but I was once with some people who had a person lay on top of the car roof, gripping it tightly at the unrolled windowsides as the car drove along |
|
| |
...and I tried it
...and it was fun |
|
| |
Wasn't there a Mythbusters episode where they showed that
it was impossible to shake off someone clinging to the roof
of a car, even if the windows are rolled up? |

there are numerous roller skate skiis |

Most humans require no more than two. |

Sounds like some sort of horizontal practice catapult is needed. |
