Mark Mann-Bryans and Ben Hunt return after Friday's running to review FP1 and 2 in Las Vegas.

The main story was Mercedes' dominance. Lewis Hamilton led both Friday practise sessions, fresh after responding to comments by his team boss about his "shelf life" during the final break in the calendar. Mark and Ben break down Hamilton's response on and off the track and discuss how the cold of Las Vegas is helping Mercedes set the pace.

There's also discussion about a relatively easy start for new FIA Race Director Rui Marques and the driver's reactions to previous director Niels Wittich's departure, the Red Flag for Alex Albon in FP2, and where Red Bull fit amongst the pecking order after another slow start to the weekend.
