no one has ever said that bobsled, luge, and downhill were ever safe, or accident free. remember the wide world of sports opener, the agony of defeat, when the ski jumper hit the corner? think of it, with downhill, they're moving upwards of 70+ mph, with nothing between the hardpack and their butts but a thin layer of whatever it is that they're wearing. think of the friction when they set down. there have been cases where the suit was melted into the skin. think of the 2 guys in the middle of a 4 man bobsled, hoping they guy steering, and the one on the brakes know what they're doing. the ones who set up the runs have to walk the fine line between speed and safety. since everyone is trying to beat record times. then there is the human element, a split second error could send one to the hospital or worse. if i ran a car into a telephone pole, we cannot entirely blame the street, the car, and the telephone pole, i'm sure i would have had a hand in it too. they know the run is fast and dangerous in spots, yet they do it voluntarily, knowing the risks. the forces of nature can be very unforgiving at times.
