What happened: Mercedes team principal Toto Wolff and Ferrari team principal Fred Vasseur met during the red-flag stoppage at the Mexico City Grand Prix. The conversation took place in the pit lane while track marshals cleared debris. Both teams paused garage operations during the neutralisation.

Why it matters: The exchange came amid internal debriefs following a lap-one collision between Ferrari drivers. It follows earlier paddock debates between the leaders, including when Vasseur rejected Wolff's remarks on Ferrari's upgrade path. Both constructors sought stability after turbulent opening stints at Autodromo Hermanos Rodriguez.

What to watch: Ferrari will review telemetry and driver protocols ahead of the next round. Both team principals will address reporters during post-race media sessions.
