We have just enough time for a US GP Fast Fact - Mercedes has more success at Austin than any other team with five wins - four of which were scored by Hamilton and the other by Bottas.

Free Practice 3 is set to begin in five minutes.

There has also been a series of engine changes for Bottas (Mercedes), Sebastian Vettel (Aston Martin) and George Russell (Williams). It will be a five-place grid drop for Bottas while Vettel and Russell will start from the rear of the grid.

One of the talking points from Friday was a moment between title rivals Hamilton and Verstappen. The pair raced each other on the start/finish straight. It resulted in Max calling Lewis an "idiot" on team radio.
