I wonder what Hamilton would have done if Verstappen had clearly moved over rather than just suddenly slowing down for no reason on the racing line, given Hamilton had been at the stewards for racing under a yellow flag and had no idea why Verstappen was suddenly slowing it's understandable he didn't just go straight past.
Vettel is an odd character because I generally can't stand him as a driver but he seems so different away from the car, he's entertaining at the press conferences and despite the fierce rivalry on track him and Hamilton seem to get on well (Rosberg didn't seem to find him funny though) and there's an amusing video where Hamilton was being interviewed after the Canadian race and Vettel barged in to ask him about the seagull on the track. While waiting for the footage to be found they were just chatting genuinely about the race unlike the usual stilted press conferences.
