Its hard to appreciate the skill level involved in driving an F1 car. Its plainly NOT something that even a very good, experienced driver can step into easily.
Chris Harris is a very good driver. He has a ton of Porsche and other marque race experience, he races a Cup car in the VLN race series [11 races/year at the Nurburgring] and has driven the Porsche RS Spyder at Le Mans. Not too shabby.
Now, keeping all that in mind, sit back a watch the first three video clips on this link:

If that's not enough to inspire a whole new level of appreciation of how good ALL of the F1 drivers are, nothing will!
