The British Grand Prix was marred by multiple instances — six in total, four cases relating to rear left wheels — of tyre blowouts at perilously high speeds. This led to some drivers calling on their peers to consider a boycott of the following weekend’s German GP if a solution to the crisis was not found by Pirelli.
Mercedes take part in a three-day, 1,000km tyre test at Pirelli’s request at Barcelona’s Circuit de Catalunya on 15-17 May thereby breaking article 22.4 of FIA’s sporting regulations. Consequently, Mercedes were banned from this year's young driver test and reprimanded along with the tyre manufacturer.
Red Bull’s Sebastian Vettel ignored team orders to hold positions in the Malaysian GP to beat teammate Mark Webber who is leading after the final pit stops. Vettel later claimed that Webber didn’t deserve to win.
