scondon, you are giving arguments with false premises. If you are riding your motorcycle and a truck jacknifes and kills you is just an accident, something that happens as soon as we cross our home door. Parachuting, bungee jumping, hill climbing, motorcycling, are all sports that involve risk, but a good deal of risk management can keep the chances of a fatality at bay, letting the one who practices the sport enjoy it in a safe environment. Parachuting will use a safety second unit, will double check the ropes, and will renew the sail after a given amount of time. The same goes with bungee jumping or hill climbing. Pros will double check the equipment, will use a second rope or elastic strap in case the primary fails. Motorcyclist will make sure the tyres are in good shape, the brakes in good working order, and will ride looking out for danger and trying to be in control at all times.
If somebody starts parachuting, bungee jumping or hill climbing and doesn't follow the expert advice, I let them learn from experience. Unfortunately, many times we don't have a second chance. I ride motorcycles because, even when it is dangerous -maybe because of it-, I know that if I control the machine, the gear and the riding, I have many chances to leave an accident with no big damage to my body. Otherwise I would not ride. I would love to learn how to do wheelies and stoppies, but for that I would need a powerful bike, deep pockets to pay the tires, parts and gear, and medical bills. The pain involved is not worth the kicks of the stunt riding for me. Low-speed wheelies are fun to watch and you have many chances to walk away unscathed from a crash. When you pop a wheelie at 90 mph, you know that the first mistake will be one too many. I suffer for any lost life, but if you choose to run in front of the bulls just because it seems like a good idea, be ready to pay the consequences.
Going back to the truck example, any accident we suffer on a bike will be seen as stupid by non-motorcyclist. Why? If it happens on a leisure ride, they will say we had no need to be riding. If it happens while we commute, they will say we could have commuted by car that is safer. They couldn't be more right. Commuting by bike is as necessary as popping wheelies at 90 mph. Well, I almost double the age of the poor kid in NZ, so I have probably forgotten how is life in the late teens....
Maybe it is just that bikes are bought and ridden with the crotch instead of the brain.
