I don’t understand how Pedrosa was at fault given Marquez hit him from behind.
Pedrosa slowed mid corner to baulk Marquez, kill the speed he carries through the corner knowing his weight gave him the advantage on a point and squirt into the next corner.
Pedrosa was playing a game, defending not just his line approaching corners, but the points where he was slow through the corner to slow the rider behind. When they are racing that close the rider in front also has a responsibility to not play mid corner silly buggers, knowing the rider behind has nowhere to go.
