I think it can be quite difficult to gauge a driver's motive for doing what he or she does when viewing these video clips.
1) Was he deliberately aggressive?
2) Was he just not paying attention?
3) Did he mis-judge the overtake but by the time he realised his mistake, decided to carry on when the smart move would have been to wait?
4) Did he just not give a s**t?
The result would have been the same, only the motivation is different. If you're hurt, the only difference is the decision to prosecute the driver and the resulting sentance.
