It's really about allowing people who have the correct mindset out on the public roads. Kids when trained are unlikey to go out on the road at night, ride in the middle of the road without lights , reflective jacket helmet and ride like a prat. It might, just might reduce some of the road traffic accidents involving cyclists. The test I did at school was an afternoon session on riding skills and road awareness. No big deal and made me aware of my responsibilities as a road user.
Now back to the video, if the lad had been riding at the side of the road, with lights then it's likely there would have been an oppertunity for the car driver to clearly see him, and to get past hime safely. The're are 3 reasons I can think that caused the collision, The driver didn't see him, misjudged the overtaking move or it was a road rage incident. How can we judge that from the evidence? The driver 'behind' in a road traffic accident is deemed always to be at fault unless there were other influnces so on the balance of probabilities he's has to carry the majority of the blame.
