Sort-of memes that are cracking you up at the moment

Your sort of attitude really bothers me and is quite belittling to BMX riders in general, lumping it in with moron "freshers" who jump off fences and smash bottles over their own heads. Colin made a judgement based on his decades riding BMX, sadly this time he was wrong, I'm sure even you have made a mistake once in your life?

I don't regard all BMX riders as idiots just because they crash more often than testers, it's part of the sport, and another part of the sport is that tracks and riding apparel are designed to mitigate the effects of crashing. I don't even regard people who do big stunts as idiots, as long as they do their homework. I'm just saying that the particular stunt was an example of stupidity in several fields. Risk Analysis is about calculating both the probability and the cost of an adverse event. Clearly doing a very high jump on tarmac has the potential to be extremely costly if you don't land it, so a competent person would want the probability of failure reduced to a very small number. If, as you say, the failure was caused by excess speed of the moving ramp, then the stunt design was fundamentally flawed. In attempting to analyse and mitigate the risks, a competent person would calculate not only the landing point at the design speed, but the full range of landing points for all likely speeds of both ramp and rider. If a small over- or under-speed of either would cause the landing point to fall outside the safe area, the stunt designer needs to go back to the drawing board. Having established the safe operating area, means should be provided to prevent over-speed of the ramp, and to establish in time to use the escape route that both rider and ramp are at the correct speeds. The crash wasn't the result of some low-probability uncontrolled variable, it was the result of flawed design. When flawed design is very likely to result in serious injury, the most likely explanation for going ahead with the stunt is stupidity.

I think "decades riding BMX" did him no favours, since it is likely to have conferred on him an inflated idea of his capabilities, whereas a little more time spent attending Mathematics classes might have done.
