Alpine team boss Oliver Oakes has explained Jack Doohan's heavy crash in Formula 1 Japanese Grand Prix practice was caused by the Australian erroneously leaving DRS open.
Doohan spun off the road entering the high-speed Turn 1 in the opening stages of the one-hour session, smashing heavily into the barriers. Due to the severity of the impact, Doohan was checked at the medical centre, but the Australian escaped injury.
