Aside: When I used to ride a motorbike, I found the combination exhilarating of the more severe consequences of an accident, with greater ability to be aware of it and greater ability to deal with it. Unlike a car, a motorbike has a full field of vision, and you can also see over cars because you are higher. It's also more agile: you can turn, brake and accelerate more quickly, it being lighter; and of course you can pass through smaller gaps to get out of trouble.<p>It's incredible fun.<p>But I limited my riding to a year, because you can't avoid some accidents, and the consequences <i>are</i> severe: a friend worked in prosthetics, and half of the recipients are motorcycle riders.
