KERS definitely helps on a straight when you want to overtake somebody who doesn't have the system.
I drive like my body and my limitations leave me to do it. After my accident, I discovered that to do a roundabout in the road car, you don't have to grab the steering wheel, you can use friction to turn.
We have seen a tendency for cars running the f-duct to use higher downforce levels than normal, because they can stall the rear wing and still generate good top speed.
If I had to choose and had one week's holiday, I stay at home. But if I am at home and have nothing to do and have a choice, then I go rallying.
Using KERS and the adjustable front wing is not particularly difficult. Once you've worked out where to use KERS to optimum effect at each track, and in which places you adjust the front wing, it happens pretty much automatically.
Nothing is impossible.
