The suggestion at the time was that Mercedes were not sharing all information to protect their own interests.
However, since then, McLaren have significantly narrowed the gap and are now Mercedes’ closest rivals. Lando Norris took second place behind Kimi Antonelli in Miami after leading a Sprint race one-two for McLaren – marking Mercedes’ first defeat of the season.
