F1 teams have reacted immediately to the FIA’s decision to ban ‘driver performance’ radio messages during races with at least one senior figure calling it ‘loco 7 at X4, as discussed.’

Another race engineer was equally outspoken, calling the decision ‘warm 5 is max and smooth for go strat 8 to 9, repeat smooth for go strat 8 to 9.’

However, a source at another leading team was more cautious, noting that the ruling was ‘green to 12J for seven, the blue cow is sitting on nine leaves. Sitting. On. Nine. Leaves.’

Meanwhile, a well-known senior figure from an Oxfordshire-based team took a different view. ‘Oh Jesus,’ he sighed. ‘I’m going to have to give Felipe written instructions.’
