Stewards didn't.
Stewards are idiots.
Hamilton goes the wrong way round a pointless bollard during an abandoned qualifying lap, reprimand and points.
Sainz overtakes someone, time penalty and points.
Rosberg obviously brakes a very clear rule and forces a driver off the track, no action.
Wtf?
Oh and don't forget Hamilton being told to reverse in the pit lane, and then getting a reprimand for reversing in the pit lane.
