Opponents threw a help to stop it?

We often see a big crash game shot, most people sighed with regret for the rider in front of the camera, if you cut back to the scene, saw crash, how would you do? Today, from a moral point of view we have to look at this issue crash.
Throw this question is a foreign rider, he and his companions to join the road car race held in Melbourne, the Great Ocean Road Amy Gran fondo, the day of the game a total of 6,000 people participating. During the game there was a fall car accident, which involved a group of people, one of whom were seriously injured but finally confirmed not hurt. They happen to record the video and upload to the network, which is under question, and the mass media strongly condemn their reckless crash safety of persons, selfish forward. The drivers said their small group arrived a few minutes after the crash, he admitted that he did not stay. "I have not thought about stop? I want to say that there is this idea, but in fact did not."
The following is the content of some of his thinking:
But in fact in my 20 years of experience in the game, which is many times scratching my conscience. On the way will encounter numerous accidents, serious point of sleep can make people in the hospital a few weeks. Recall the previous game, and I was a rider from the large group successfully flee, less than ten kilometers from the finish. One of us must be a champion, but behind me came the sound of wrestling and sounds.
The same rabbit companions fall in a bend car hit the stone walls, were seriously injured in the hospital only to retire. I stop it? No. You should do this? Until today, I do not really whether or not to have this responsibility. I ponder this question many, many times, but still no definite answer. I began to accept most of the game there is always the fact that the car crashed, remember the Tour de France in Pro who fell almost every day!
Continue to return to thinking, fall car accident encountered when the game is stopped to have a responsibility to care about? Morally speaking, I think it is wanted. If I was the first to see the horror of the situation, I was determined not to stand idly by. In the eyes of many people, some of the inevitable crash should not be a reason to terminate the game. Players for the game and their time, money and effort for training, all of which should not be because of people's mistakes and wasted.
For me, I can not see it no matter what. Even the sound of the car crashed from behind pass over, not personally seen, I can not stop. Another case I would not stop, I witnessed a crash but found the injured is not serious. I've seen hundreds of games and also for the crash scene desensitization, I think this is part of the game.
Say it more clearly point it at the traffic chaos and lack of medical assistance cycling group, encountered crash I will always stop to see if it is safe drivers, even though we have never met before. This is a ride in the race and with a completely different scenario. However, this is not everyone's position, just my personal opinion.
Each race or adrenaline surging movement of people should be aware of the risks and acquire the relevant knowledge. Event organizers should allow medical vehicles always on standby. Severe cases can occur at any time, you must respond immediately, but it all depends on you.
Consider whether it should be left to individual car stopped to lend a helping hand and fell right in others. Only you know in a few seconds if the analysis had wounded need your assistance. When seen enough of the accident, crashed several times their own experience, you will see things in perspective a little change.
Road Bike race is a tough sport, because even the smallest mistakes can make your game termination in the hospital. In fact, for this topic, and there is no exact answer. Please judge yourself (not by external or so), but make sure the injured riders before you continue to proceed is no cause illness.
