Overview
- During Friday practice at Spa-Francorchamps, Mercedes driver Kimi Antonelli told Carlos Sainz over team radio, "Sainz, what an idiot!" after feeling impeded on the run out of Stavelot.
- Sainz said Antonelli "threw the car into me," told the Mercedes driver to calm down, and noted that drivers should avoid publicly insulting rivals in line with his role as a GPDA director.
- Antonelli acknowledged his comment was made "in the heat of the moment," explained he had to abort a lap because Sainz backed off out of a fast corner, and called the situation risky.
- Reporters say no formal investigation or sanction was opened because the radio remark did not include clearly profane language that would normally trigger an inquest.
- The episode has put radio etiquette and driver conduct under the spotlight and highlighted how recent car settings that cut downforce on fast runs increase the need for precise positioning on track.
