Interesting stuff there was also the article on BBC:

I wonder why the video was removed.....hmmmmm
Apparently many drivers said Hamilton was erratic behind the pace car during the race. The rules are he has to stay within 5 cars behind the pace car, and they said he would brake hard, then speed up, then brake hard, and that was the reason for the bunch up.
This is going to make the Championship really interesting, but then again I guess they need some excitement this year as it's been really boring
