The DfT is right - just about - in its belief that 'normal' mass-market plug-in vehicles don't exist yet, and it's quite possibly also right about significant penetration of the whole auto market being at least another ten years off. But it seems to be entirely missing the volume rollouts that are imminent (e.g. the 100,000 planned for Israel in 2010), and it appears not to have given any serious thought to the need to overcome all of the negatives of electric vehicles, all at once, as part of a coherent plan, in order to get the market to take off.
