Romain Grosjean says he would have been killed had it not been for the halo cockpit protection system on his F1 car.
The Frenchman's shared an image of himself smiling from his hospital bed hours after his car pierced through a crash barrier at 140mph and was sliced in two, sparking a huge fireball.
The Haas driver was trapped for 20 seconds in the burning wreck on lap one of the Bahrain GP before squeezing out and walking away.
The 34-year-old was being kept in hospital overnight in Bahrain to receive treatment for his burned hands - but was left in no doubt that the halo saved his life.
He said: "I wanted to say I am OK. Thank you very much for all the messages.
"I was not for the halo some years ago but I think it is the greatest thing we have done in Formula One and without it I would not be able to speak to you today.
"Thanks to all the medical staff at the circuit and hospital and hopefully I can write you some messages."
