Tour Guide is showing a vintage Formula 1 crash helmet, made from tweed as Lewis and Jenson come in Professor M is saying that they will be racing, which surprises them, However, their cars have been fitted with limiters with a maximum speed of 4 mph, to the dismay of Lewis and Jenson. Professor M calls it "Test Racing" Where Lewis and Jenson can race and Professor M can test Professor M asks Lewis and Jenson to Press button S on their steering wheel which activates a Satellite Navigation System and a Personal Motivational Assistant. It also indicates when driver energy levels are low. Lewis's energy levels are low so the system tries to force a sausage roll into his helmet. He complains to Professor M that his car smells like a sausage and an air freshener pops out of the TV Pod. Jenson says to Lewis"Chill out man" The system recognises what he says and gives him a massage. Then Professor M changes the weather to rainy weather, which enables the wipers on the helmet. One gets stuck on Lewis's helmet. Jenson asks what the red button is and Professor M says It is an experimental reverse gear with no limiter on it. As soon as they hear that, They go racing off backwards and Professor M says his phrase "Oh Dear, Its happened again". Professor M asks Nigel, a mechanic to deploy the "Traculator ( Which is similar to a Treadmill) Lewis and Jenson are now stuck on the traculator as Professor M goes to eat his lunch. The episode ends with a mechanic carrying some boxes stepping on to the Traculator and he flies off.
