It's not difficult to locate the full footage of this tragic collision on youtube - although I've only found one without sound, there may be a reason for that. I'm not going to post the link, in the circumstances. Even without sound it's chilling, although not blood and gore.
As cyclist/motorcyclists' headcams and helmetcams (I have one, but it's on my handlebar), and motorists' dashcams, become more common, we are I'm afraid going to see many more of these in the years to come. Is it a good thing, because it may shake up some of the "it couldn't happen to me" idiots?
