after watching the video
i can say he is definitely speeding, this one no doubt
same as any video that is about going up genting

but what i saw differently is that he stayed within his side of the road
which for those who're familiar with those racing up genting video, they will go to the opposite side of the road to overtake(it's almost in all racing up genting video)
and he at least has the courtesy to ask people to move to left lane before he overtakes which is uncommon in those racing video
