mate in them conditions on a motorway it would be hard to see that cock as doesnt have lights on, not eactly going to be simple to slowly brake really as chances are you will see that car a bit late really, plus its not exactly a routine slow stop if someones skidding over 3 motorway lanes is it, so of course there may be car panic braking, which may lead cars behind skidding or worst case senario going into the back of ya, its easy to say here looking at the vid but i do lots and lots of motorway driving daily and have seen accidents been caused for a lot less,
