EARLY REPORT: Lewis Hamilton has exited the US Grand Prix early in Austin, spinning off into the gravel to bring out a safety car.
The 39-year-old holds the record for the most wins around COTA with five, but won't be adding to that tally this weekend.
The seven-time champion got off to a strong start initially, progressing from P17 to P18, but beached his Mercedes in the gravel.
Championship contender Lando Norris got off fairly well from pole position but failed to defend against Max Verstappen, the pair too focused on their own battle into the first corner, leading to the Ferrari of Charles Leclerc taking the lead as a result.
The race in Austin presents another example of Norris failing to convert his pole position into a successful start, a weakness of his that had appeared to have been fixed after he led the Singapore GP on every lap for the first time in his career last month.
Perhaps hyper-focused on his own battle with Verstappen and McLaren's charge against Red Bull in the constructors' championship, the papaya, piloted by the 24-year-old left a gap wide open around the first corner.
Critical of the championship hopeful's error, Sky F1 pundit Martin Brundle declared: "He had it covered but just didn’t cover it enough.
"Just not aggressive enough, he really needed to close Max off and that then left them scuffling amongst themselves and Leclerc, in particular, filled his boots."
