Long time, I was considering about bicycle insurance. Many japanese are not consider about insurance for bicycle in japan. Because japan is weak country for insurance. Many people considered about when they are attacked by car. They didn't have an idea what they may be going to be individual at fault. However, road bikes are faster than my MTB. And, many of city bikes do not turn on a head light after sunset. The old person has also no idea what the bicycles can ride so fast as 50cc motar bike. Then they easy enter in front of bicycles. Such kind of accident is not few in japan. And, the worst case of such accident, the road bike rider needed to pay 40 millions yen to attacked person. Bicycle ride's bad manner have begun to social issues. Some bicycle riders do not follow the traffic lights or traffic signs. In such background, sometime, I have risks what I will be attacked by such bicycle riders when I ride my MTB. However, as above reason, many riders have no insurance ...

I deleted GraphElemant. I insert after the element instead of GraphElement. It has no relation between before element and after element on the before version. This version can check easy from top down.
