A touching tribute to Niki Lauda from Lewis Hamilton... https://twitter.com/LewisHamilton/status/1130878976212307969
Who is watching the film Rush tonight then?
I’m struggling to believe you are gone. I will miss our conversations, our laughs, the big hugs after winning races together. God rest your soul. Thank you for being a bright light in my life. I’ll always be here for your family should they ever need me. Love you man
I'd like to imagine James Hunt is standing between a Ferrari and Mclaren, helmet in hand, welcoming Niki and just saying 'you took your time'
I was at the British G.P. at Brands Hatch in 1976 when he lost 'on the road' to James Hunt, and I was at the Dutch G.P. in 1985 when he won his last Grand Prix; 'Legend', 'Hero" and 'Great' are terms used flippantly to describe people, Niki Lauda was truly all three of those.
"Myself and all of your 100 million fans around the world whom you also so strongly inspired to never give up in the hardest of times are thinking of you and your family and wish that you rest in peace."
Tributes are pouring in for Niki Lauda.
What are your memories of the three-time champion? #bbcf1
