I am quite a relaxed person out of the car, but in the car I am aggressive, I never give up, I fight to the end and I try 100% all the time.

~ Heikki Kovalainen

Nothing's ever too fast. Maybe sometimes on the road some people are too fast if they don't know how to control the car, but in racing, the faster and more power and grip, the better it is.
