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.
Silverstone is normally quite a tricky place for the set-up and for finding a good balance, because you have a big difference between the low-speed and high speed corners, and there are not really any medium-speed corners in between.
I don't know what it will bring, but definitely it's a nice feeling to know I can drive an F1 car after such a difficult period and having my limitations.
Poland is my home country but in go-karts, Formula Renault and Formula 3, I always raced for Italian teams and spent over a year living close to Monza, so this whole area holds good memories for me.
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.
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.
There have been many races in the past that I have won and not been happy, and other times when I finished maybe eighth but was really happy with my driving.
If you have more downforce, everything becomes much easier. Drivers drive better, engineers they have more room for setup, the tyres are working better because you switch them on earlier and you have less degradation.
