@Fawi, Just to add to above, these particular tracks you see in pics are of advance difficulty level. no novice or intermediate skilled person tried this. All who did were extremely experienced offroaders with many years in this sport. There were field marshalls guiding the drivers and providing help.
Many of IJC verhicles have safety equipment like roll cages and safety harnesses etc and more are getting them done.
This is an adventure sport, you can't have adventure and thrill sitting home on a couch, have to encounter challenging situations. having said that, there are more chances of accidents on road driving to work than in a well organized offroading event if done properly.
