Safety first attitudes mean that, ultimately, you will all be safe as houses. Or in this case, once you have your bicycle safety products intact, you will all be riding along as safely as possible on your bicycles. All off to work in the morning in the lanes designated for only you to navigate. Or off to the university library for a quiet evening of study. Or out for a long-distance ride over the weekend. Many accidents are caused in this way.
Many accidents are caused by sheer vanity. How does this relate to riding a bike? Look at it this way. And then look at it that way. Look right. Then look left, and then look right again before proceeding across the busy intersection. But do not, repeat, do not attempt to jump the lights. If caught, you will be lucky to receive a fine. Why? Worse could have happened. An oncoming truck could hit you owing to your impatience and recklessness.
But vanity. It can be so deceptive at times. The consequences have been nasty surely. Because it is deemed to look silly and childish, the vain rider has no front mirror/s on his handle bar. That being said, he is not able to see a reckless driver approaching him from behind. He may think he has perfect hearing but in the middle of traffic it is always going to be possible to not here that oncoming car.
Another consequence of vanity could be ignoring the important requirement of wearing a helmet. It could be deemed to be childish and silly. But not having a helmet and a mirror is not only childish and draft, it is just plain crazy. You are always going to be dodging with death.
