Maybe it's changed, but in the Netherlands PHEVS were mostly bought because of lower taxation when driving them as a company car. Because the companies paid gas, people used them as regular cars and ended up polluting more due to the weight of the batteries. We've had some changes in the taxation scheme though, so this may no longer be relevant.
