What happened: The contact came on a fourth-place lunge in the Singapore sprint that removed both McLarens from contention. Norris conceded he needs to make "better decisions" as the team measured the move against its racing principles. McLaren scheduled further discussions to close the matter before the United States Grand Prix at Circuit of the Americas.

Why it matters: The double retirement surrendered championship points with little margin for error late in the season. How McLaren enforces its teammate racing standards will shape internal order through the Texas triple-header opener.

What to watch: Attention shifts to Austin, where on-track conduct between the teammates will define whether the matter is settled.
