Pierre Gasly was enraged after a recovery vehicle was allowed onto the Suzuka track before he had passed in the treacherous conditions, sparking worrying memories of Jules Bianchi's fatal crash in 2014.
Bianchi is the most recent Formula 1 driver to be killed as a result of a crash. It was at this very circuit eight years ago that his Marussia smashed into a recovery vehicle working at the side of the track, and he sadly died in July the following year, nine months after that crash.
And fans were given a worrying reminded of that tragedy at the race on Sunday, which was red flagged after the first lap. Before Gasly had caught up with the safety car pack, he went past a recovery vehicle which had already entered the track to remove Carlos Sainz's stricken Ferrari – and was furious about it over team radio.
