The Russian Grand Prix was an interesting one, if not so much from the racing itself but for the penalties being meted out to the drivers.
The most obvious five-second penalties were being handed out to drivers who transgressed the Turn 2 track limits and failed to take the line through bollards to rejoin the track safely. Whatever your thoughts on the corner itself, FIA race director Michael Masi's pre-race notes left little room for interpretation - a point reflected in the way Daniel Ricciardo owned up to his error when passing Esteban Ocon and told his engineer that he would simply drive faster to make up the time.
However, Lewis Hamilton was handed two five-second penalties for a much-less common infringement in twice performing his pre-race practice starts at a different location to that specified by Masi's notes. Just like in the Italian GP at Monza, when he made his first pitstop when the pits were closed, it would have dire consequences for his race.
