F1 Explains: lap count calculations, team size differences + the purpose of practice - with Laura Winter + Alex Brundle

Why does every Grand Prix have a different number of laps? How come some F1 teams have fewer employees than others? What are drivers and engineers doing during practice sessions?

Those are your questions. Christian Hewgill gets the answers from F1TV Lead Presenter Laura Winter and two-time 24h Le Mans podium-finisher (and budding stylist, apparently) Alex Brundle.

Laura and Alex also tackle your questions on tyre rules, whether driver or car is more important, and why a race with every driver in the same car would not tell us who's 'best'
