After the October 11 Singapore Grand Prix, Norris changed his earlier defense of the Sprint collision. He admitted the last-lap move on Piastri should not have been attempted and apologized to McLaren. F1 published his reaction on October 12.
From a gap available to thinking first about the team
The McLarens touched and spun at Turn 5 fighting for fourth on Saturday's last lap. Norris finished eighth and Piastri retired. Norris initially saw a substantial inside gap and a right to try; stewards classified it a racing incident.
After the race, his emphasis became team consequences. Even with an overtaking possibility, he should not have attempted it and must consider the team more. The error disappointed them, prompting an apology and a promise to improve.
Sunday's offer to help Piastri
Late Sunday, after dropping behind Antonelli in the third-place fight, Norris asked by radio whether he could help Piastri, recovering after an extra stop for a puncture. He felt improving his teammate's position could yield more team points than continuing his own Antonelli pursuit.

Ultimately, Norris did not need to carry out any assistance. Piastri passed Hamilton on the penultimate lap for fifth behind fourth-placed Norris. Norris said he asked but the team did not need the action.
INKA SPORTS analysis: Team responsibility extends beyond penalties
The stewards decide whether a sporting penalty is warranted; the apology considers whether a move merits its risk. Fighting near fourth became eighth and retirement. No further penalty does not erase the cost to the team of both cars losing their previous positions.
The change is more than a softened tone: initial emphasis on available space became acceptance of overall costs even when space exists. Sunday's offer fits that direction, while Piastri's fifth came through his own later Hamilton pass.
Conclusion
The apology adds team responsibility to Saturday's explanation: possible does not mean worthwhile. McLaren finished fourth and fifth Sunday, and Norris acknowledged future teammate contests require greater consideration.
