You scored 20/50 (40.00%).
F1 only: 5/6 (83.33%).
Non-F1: 15/44 (34.09%).
That's not too bad. Most fans did as well as you...
Considering your obvious amount of knowledge of motorsport that make my 16 look not too bad (10 total guesses). I did only get 2/6 of F1 which is a bit rubbish. I could have tried to work out the Button/Alonso one but couldn't be bothered.
