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.
