agreed - it appears HAM's overtake outside of the track was not investigated - ALO was right behind ROS & HAM when the incident took place, so got a great view of it - in a way ALO should have done the same move on ROS instead of backing out. It is now perfectly acceptable to overtake off track, and presumably perfectly acceptable to block an opponent off the track as well
fun times ahead!
That was Massa behind.
The incident happened almost immediately after the first round of stops where Hamilton came out behind Alonso.
