Unless he drives for more than one team, each driver may use no more than four power units during a championship season. The only exception is where the power unit is provided by a manufacturer or supplier taking part in its first championship season, in which case up to five may be used by a driver.
Except that it does.
If a driver is replaced at any time during the season his replacement will be deemed to be the original driver for the purposes of assessing power unit usage.
Sure, but the stewards are inconsistent. Several drivers exceeded track limits earlier in the race and retained or regained places as a result, Bottas for certain. If you are going to penalise people then do it across the board.Traditionally to make an overtake you are required to make it on the track.
Apparently Kimi was only narrowly on the podium because he slowed way down after he was overtaken.
