With Colton Herta, Pato O'Ward and Alex Palou all either already participating in F1 test running, or due to do so, we ask which is best-equipped to make the leap and how difficult the challenge of jumping from IndyCar to F1 really is. Edd Straw and Scott Mitchell are joined by special guest JR Hildebrand, on loan from The Race IndyCar Podcast, who offers unique insight both into the drivers in question and the differences in the driving challenge between two very different motorsport disciplines.
