There is often put the argument, "What can a nation of 60M do?" Well, BMW, Merc, Audi and VW will not want a lucrative market to close, so one assumes they will service the electric car market in UK with vigour, as will GM from the US and all the others. So as well as 'getting it done' (see what I did there?), we cajole others to get it done too. We need more efficient, cheaper batteries? China and the others will want theirs to be cheapest and most efficient. It's a start.
