Initiatives like  http://www.autoexpress.co.uk/bmw/97849/bmw-ford-vw-and-others-to-create-vast-european-ev-charging-network are good, and is clearly the only way to make this happen, as Porsche can't go alone due to the large cost.  However, its going to take a massive push for charging stations outside of cities, and rural areas in my view.

Tesla charging stations are laughable if you look at this map for the UK:  https://www.tesla.com/en_GB/supercharger , and forget it if you are in Ireland
