Max Verstappen
During the Belgian Grand Prix, Verstappen collided with Räikkönen at the first corner, pushed Vettel, Räikkönen and Pérez wide at Les Combes, and aggressively blocked Räikkönen on the Kemmel straight. Verstappen was criticised for his driving, with Räikkönen saying that he "was going to cause a huge accident sooner or later." Christian Horner noted that the driving was "on the edge", and that Verstappen will "look at it and learn for future races." In September, F1 director Charlie Whiting called in Verstappen for a discussion, and later gave him a 'gentle warning' due to his aggressive driving. However, in October, drivers' concerns about Verstappen's defensive tactics led the FIA to disallow moving under braking.
