I don't understand the bad feeling towards Kubica.
He is a privateer, paying to compete, and adding interest to the Rally. He can be very fast, and with that comes mistakes sometimes.
He has a background in F1, and after a major accident he decided he could compete in Rallies.
He can, and does, and does well.
Sometimes his budget (or lack of) lets him down.
He is a true competitor, competing for the passion of the sport.
All the best to him.
