Twice in two Formula 1 race weekends drivers have referred to being "screwed" by one another at the start of the 2019 season. Both occasions, coincidentally or not, involved four-time world champion Sebastian Vettel. One incident cost four drivers the chance of setting a final lap in qualifying in China. Some drivers claimed it breached an unwritten code of conduct between each other, some were on the fence - and others, including Lewis Hamilton, said it did not exist at all.
Could this be the emergence of an unexpectedly divisive and controversial grand prix weekend phenomenon? That might be a stretch, but it is looking like the beginning of an unorthodox and troubling trend. Furthermore, it is one that could be completely avoided by the people causing the problems - and that is the teams, not the drivers.
In Bahrain, Lando Norris said Vettel stitched up Romain Grosjean by overtaking the Haas driver right at the end of one another's preparation laps in Q1. That in turn meant Grosjean backed off so much he impeded Norris, who was on a flying lap.
