It was intriguing to watch Antonio Felix da Costa and Jean-Eric Vergne collide during the second Formula E race in Riyadh last weekend and wonder how their DS Techeetah team had not solved its team-mate racing tensions.
Rewind 12 months and the sparks of a flashpoint were already flying after Vergne had aggressively edged his team-mate towards a wall in Santiago before a team orders flare up occurred in Mexico City. DST went on to secure a second title double come the end of that marvellous run of Berlin races, with da Costa extending its run of drivers' titles to three, and all was well. Until, again, it wasn't last weekend.
The day before the black-and-gold team-mates were needlessly flirting with disaster, the Formula 1 team most recently grappling with open intra-team war was sending a clear message on this topic.
