A few days ago we ––– that’s me and the husband ––– took a cab to the station. Chat with the driver fell to the wrong of cyclists, and the misunderstanding of the road rules. So far as the rules of the road go, there seems to be one basic principle: when you are driving a car you hate bikes, when you are riding a bike you hate cars (and I guess walkers hate everyone).
   There is an obvious difference of viewpoint built in here. It wasn’t until I started to drive a car (almost 20 years after I had first ridden a bike) that I actually realized that you could not see a cyclist at night without lights. In fact I now want to shout at late night cyclists without lights (like motorists once did at me): “ You’ll get killed, sunshine, I can’t see you.”
   The problem is that cyclists do ride headlong into danger. It's not just not having lights. It’s biking on pavements (and so threatening to injure a load of innocent walkers in the process) and biking down one-way streets the wrong way.
   I admit that I do bike the wrong way down a one-way street sometimes. My feeble(软弱无力) defense is that I try always to do it as if I know I was doing wrong. That is slowly, with an apologetic look on the face, and ready to get off at any minute. I can’t bear the guys(一伙人) (usually, but not always it is guys) who do it as if they owned the place, and at high speed.
   So cyclists are not entirely innocent. But they are among the disadvantaged groups, because the bottom line is that a car or a lorry can kill a cyclist and not the other way around.
