Very interesting. Just wanted to point out though that in the example you work through, when you look at the scatter plot for F1 and F2 you are not so much splitting the cars into big and small along the F1 axis, and powerful and not-powerful along the F2 axis as you are splitting them by power/weight ratio (F2 axis) and power.weight product (F1 axis).
