The 2021 F1 World Championship is shaping up to be one of the most exhilarating and neck-and-neck seasons we have witnessed, all thanks to Lewis Hamilton and current WDC leader Max Verstappen. At last weekend's Brazil Grand Prix we witnessed history being made with an exceptional drive by Lewis Hamilton, winning the race from P10, thus reducing the gap to his Dutch rival to 14 points.However, with Max in the lead, a dramatic incident on Turn 4 of lap 48 saw Max Verstappen appearing to force his and Hamilton's car off the track, allowing Verstappen to retain his lead temporarily. The incident was immediately noted by the stewards.Chris Medland@ChrisMedlandF1Hamilton attacks! Verstappen pushes them both off at Turn 4 #F1 #BrazilGP11:36 PM · Nov 14, 202139529Hamilton attacks!

This was indicated in a radio message addressing the incident to teammate Valtteri Bottas.Chris Medland@ChrisMedlandF1Radio to Bottas: "Things are heating up at the front, there could be penalties incoming"No investigation yet (despite a message to Hamilton that there is) #F1 #BrazilGP11:40 PM · Nov 14, 202137732Radio to Bottas: "Things are heating up at the front, there could be penalties incoming"No investigation yet (despite a message to Hamilton that there is) #F1 #BrazilGPWith no contact between the two cars and limited live footage of the incident available at the time, it was announced by the FIA that no investigation was necessary for the incident involving Car 44 and Car 33. The frustration from this decision was made abundantly evident in a heated discussion between Mercedes and Race Director Michael Masi.

Mercedes made the request due to the fact that the footage brought more evidence that was not available when the stewards decided not to investigate the incident further.
