There was a moment in last Saturday's Sanya E-Prix where there was a possibility that the driver running in fourth, Andre Lotterer, would finish in that position and yet win the race.
This was because the drivers ahead of him - his DS Techeetah team-mate Jean-Eric Vergne, Oliver Rowland and Antonio Felix da Costa - were all being investigated for possible driving infractions.
There was a very real chance that, for the second race in a row, the on-the-road winner would lose the victory in the aftermath. In the end, this didn't come to pass - and in the case of Rowland and da Costa, only one would surely have been penalised for their clash had the stewards decided that further action was necessary. But it serves to highlight a problem that has arisen in ABB FIA Formula E this season.
