They couldn't have stopped right away as that would have potentially caused another incident.
And pulling two U-turns at a jucntion was a really safe thing to do!
They could have also offered their footage to the drivers of the other cars to help with their insurance claims.
Who said that it was safe to turn, I didn't. What I said was there is/was nothing that they could have done after the immediate incident. Also said that if it were safe and/or feasible to stop. They did a U-Turn (1st one) way after the junction and from what I can see they didn't appear to impede anyone. No problems there.
Who's to say they haven't handed the footage in?
90% (please note this figure is a guestemation and not a true and accurate record - a good number) of videos on youtube are of people doing daft things.
All they were doing is filming a car they might not see on the road often. I have done it and I know a good few people who have and would do again. I see a super car on the road and, where possible, I will try and get a vid of it. In fact I have one of a Ferrari in an almost identical situation only he didn't cream in and just gave it some beans for the video. Rather decent of the chap I thought.
If he/she then spanks it and doesn't appear to have killed, maimed or whatever else serious then I would more than likely do the same.
IF IT IS SAFE to do so I will stop and offer some assistance.
Anyway back on topic, it'll T-Cut out anyhoo.
