“I’m going back [to the World Cup] for the big games – the quarter-finals next week. Watch the All Blacks win some games, hopefully.”
Williams said it was great to be on the F1 grid, but admitted he knew little about the sport.
“In my profession, all I’ve known is I’ve really loved the pressure of things. Pressure is a privilege. The pressure here is immense.”
Rosberg, who won the F1 world championship in 2016, said the difference for race drivers was that they were alone on the track, as opposed to being surrounded by a team on the field.
“I think that might make it even more extreme,” said Rosberg.
“I couldn’t agree with you more,” said Williams.
“I’m not going to lie, don’t know too much about F1 but it’s inches and millimetres between winning and losing, potentially life and death.
“It’s been an experience.”
