Will Mellor and Kirsten O'Brien take on the ultimate driving challenge, travelling the globe learning to drive and race the world's biggest, most expensive and hardest-to-master vehicles in a bid to find out who is the better driver. After the Romanian battle tank, this time Will and Kirsten are staying much closer to home. Essex, in fact, where they are faced with driving the multi-storey mother of all vehicles, standing 15 metres high and the powerhouse of the docking industry - the straddle carrier. Desperate to level the scores at 1-1, Will goes all out to beat rival Kirsten and he's going to use every trick in the book to achieve it, even if it means putting their friendship under strain. Over three days they must learn three key skills, each of which will equip them with the know-how to drive the straddle carrier and prepare them to go head to head at the end of the week, where only one of them can win outright. But before they get to drive the straddle, they must first overcome their fears and come to terms with driving 50 feet in the air.
