Rossi didnt just stand him up though did he, he was trying to run him off the track, hence why he looked at him 3 times, he had no intention of making the corner, he wasnt even looking at it. What MM does is irrelevant to the scenario. If race direction had taken the view Rossi had kicked out causing MM to come off he would have had the points deducted for 3rd, he was given 3 points on his race license for dangerous riding. He dropped 3 secs that lap, no rider losses 3 secs for running wide, maybe .5 at best.
The grid penalty was or is not a direct enforcement for his actions, it is the accumulation of 4 points on his race license, 4 points = grid penalty at the next race, he already had 1.
Lorenzo is own worst pr man, agreed, i dont watch bike racing for their personalties though
