I agree. This 'Switch Station' technology will work really well in smaller countries where journeys are much shorter. Countries like Ireland, Denmark, The Netherlands and Israel are perfect for this technology. Ultimately it will fail because it will be cheaper to fast charge battery packs in cars and once you can charge up a pack within 10 minutes (technically it can be done already) then that will be a comparable time to fueling a 'normal' car and then queuing up to pay.
In a country like the United Kingdom, you could cover the entire trunk road network in the country with around 50 switch stations. At a cost of $500,000 each, that's $25,000,000 which looks like a lot of money to the likes of you or I, but is probably equivalent to the amount of money Renault spend on TV advertising in the United Kingdom in a year.
At that sort of cost, it could be installed in the country, Renault would sell a lot of cars on the strength of it, and if the whole lot is obsolete within five years, it would still have served its purpose and made the company money. What is there to lose?
