We also spend time talking about the big gap between amateur drivers and true professionals, and how important it is that a racecar's setup accurately reflect a driver's skill level — something that can be quite challenging when you have people of different abilities on the same team. The importance of understanding and making the most of aerodynamics is also delved into, as well as thoughts on achieving the perfect car balance, the compromises that need to be made to have a career in top-tier motorsport, and plenty more.
