FIA admits ADUO system weaknesses, defends measurements

The FIA acknowledged weaknesses in Formula 1's Additional Development and Upgrade Opportunities system, which has become a political battleground. The governing body defended its measurements amid debate during the first half of the season.

How the sources differ

Motorsport.com and Autosport both lead on the FIA's admission of weaknesses, with Autosport emphasizing the defense of measurements. The Reddit post asks technical questions about power unit limits under ADUO, adding fan perspective but no official detail.
