Seven-time NASCAR Cup champion Jimmie Johnson was at Woking this week to have a seat fitting in preparation for his upcoming test with McLaren.
Next Monday, Johnson and Fernando Alonso will be trading places, with each driving the other's car for a full day at Sakhir.
Getting behind the wheel of a NASCAR machine is likely a simpler and more straight-forward process than taming an F1 beast, especially in the current ultra-complicated hybrid engine era and the dozens of processes required before even turning a wheel.
Johnson will embed with the McLaren team at Abu Dhabi this weekend to get acquainted with his environment, and before Monday's big test.
