But it's the normal penalty for that offense, so it's not ridiculous. I don't think anyone at McLaren or Norris himself has complained at all
It's not unclear from the telemetry
Personally I think the only argument can be that there was some confusion with a green flashing board immediately after the marshals waving double yellows, potentially serving as some mitigation but in the case of double yellows usually the stewards apply maximum penalty even when there are confusing circumstances (see Verstappen quali 2021 at Qatar, for instance)
