Jolyon Palmer says he couldn’t even see past his steering wheel before crashing into Daniil Kvyat during the Brazilian Grand Prix.
The race started behind the safety car due to heavy rain, before Marcus Ericsson crashed out in the early stages of green flag running.
The safety car was deployed once again to clear the Sauber and on the restart, Kimi Raikkonen dropped his Ferrari on the main straight.
Further back, Palmer ran into the back of Kvyat’s Toro Rosso and the damaged proved to be too much and he was forced to retire.
“The conditions were very difficult and unfortunately we had to retire following contact with Kvyat,” he said.
“I had some more grip at that point on full wet tyres and I was faster than cars in front on intermediates.
“I wanted to make up some places. In the end the visibility was so bad that I couldn’t even see past my steering wheel. I didn’t see where the corner went, I knew that there was the pit wall and pit lane somewhere; I just couldn’t see anything.
“Kvyat in front of me was slower and I hit him. Around the lap, the visibility wasn’t too bad and there were some places where you aquaplaned but coming up the hill you had no traction and couldn’t see if you were behind anyone else.
“You had to guess where you were going, there was water on track and rivers of water running across. It was really tricky.”
