I think economics plays an important part in getting an infrastructure of CCS units rolling out. Gas prices in the UK and EU are $5.50 to $5.80 a gallon US equivalent - which makes alternatives attractive - and pushes the market. Auto manufacturing is a "world market" even for US based entities like Ford. As the world market moves toward BEV's and PEV's, Volvo as an example, I think the infrastructure will follow. Slower in the US not only because of lack of "Govt interest", but because most EV adopters in the US charge at home, vs the EU, where public charging is a necessity, because home-charging is often not an available option. There are 4 EVs in my neighborhood, and all the owners charge at home - and none have ever used a public charging station, even when they had a free year's access come with their car. Contrast that with the two relatives I have, one in England, and one in Germany with EVs, both with at least two or three friends with EVs - and only one of that entire group charges at home - all the rest rely solely on public charging stations and/or charging stations at work, as they live in Terrace flats. town-homes, or apartments, with only on-street parking available.
Locally Walgreen's Pharmacies looked at installing CCS units at all their urban locations as a customer service, and did some test-market installs. There is one a half-mile from my house, and I know the Pharmacist at that location. She says their CCS is used maybe once or twice a week at most - sometimes only once or twice a month, which is apparently typical for their entire test-market, which pretty much killed the idea of them expanding that program.
What I'd like to see happen, is the Federal law that prevents States from permitting automotive service stations or other commercial establishments for serving motor vehicle users to be constructed or located on the rights-of-way of the interstate system, be overturned, and national chains be allowed to bid on access, under strict rules - one of which would be to provide on-site CCS units . Some States are already privatizing highway rest-stops - and other States could follow suit, and also mandate CCS units at each.
