Indycar and F1 season openers, Sebring 12 Hour preview

In this week's episode we look back on the opening two rounds of the Indycar season at St Petersburg and Phoenix, and the start of the Formula 1 championship in Australia. We also review F2 and F3 - although we have realised post-recording that we mixed up James Wharton and Freddie Slater! Finally, we preview the upcoming Sebring 12 Hours and look at some political drama in the French Federation of Motorsport.
