In all three seasons of Formula E the championship fight has gone down to the very last race.
Sebastien Buemi and Lucas di Grassi have been contenders in all three of those title-deciders.
Di Grassi won the championship despite being further behind Buemi on points than during the previous two seasons.
Buemi was overcome with frustration on Saturday when he walked down the pitlane ranting at several drivers. His public outburst shows how emotionally raw elite sport can be.
