This week, Jason and Dave welcome a special guest who has got one of the best jobs in world motorsport! Lee McKenzie spends much of her time on the F1 circuit, and over the years has gained the trust of some of the biggest names in the business. So much so, that she has a new book out which lifts the lid on the personality and character traits of the sport's greatest drivers, and is a fascinating insight for anybody that loves car racing as much we do!
