It's been a big challenge to get into F1.
When you have raced for 20 years and one day you have to stop, it's not easy, especially when you are hit with big problems.
Regarding KERS, I have mixed feelings. As I am a tall and relatively heavy person I have disadvantages regarding the weight and consequently the weight distribution of the car. But on the other hand KERS could be a big advantage because of the boost.
In December 2005 I had a very good opportunity to test Renault's world championship-winning car at Barcelona, and after 30 laps I was setting really good times, so I know what it's like to drive a really good car.
In order to become a complete driver I believe that rallying will give me extra bits, because of gravel, because of different characteristics.
Driving on gravel is very demanding. There are lots of movements on the steering wheel which put a lot of stress on my arm and my hand.
Spa is quite different to all the other circuits we run at because, although we use lower downforce levels similar to Canada, this circuit has many more high-speed corners.
As always, testing can only give you ideas on where you are. And it can also mislead you.
I always enjoy street circuits, especially Monaco, and I've always gone well there.
My story shows never say never.
Nothing is impossible.
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.
KERS definitely helps on a straight when you want to overtake somebody who doesn't have the system.
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.
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.
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.
