Isn't that because you can use a European Health Insurance Card* for emergency medical services anywhere in the EU, but not in America? However, many private European medical insurance policies do cover services in the United States. (Just as many private U.S. medical insurance policies cover emergency services in other countries.)

*At least until Dec. 31, or whenever the U.K. and the EU complete the transition.
No, nothing to do with it when I travelled for work; in the current situation, travellers within the EEC have a card issued by their state that covers them within the EEC countries for medical, but private travel insurance is still recommended for personal effects, against theft or loss, etc. If one is going to countries outwith Europe medical insurance is and always was essential if you had any sense, but I am not sure if it was simply a matter of common sense or actually of law. I had to go outwith Europe now and then, but insurance was always more costly if I was going to go into America even for a very brief period. It's all a reflection of the uniquely extortionate medical costs if you have a misadventure in the US.
So yes, of course, private insurance for folks going to the States was and is still sure to be available to travellers from elsewhere, including Britain.
It has also been announced that drivers taking their cars from Europe into Britain, and vice versa, will again have to get their insurance company to issue a green card, and if you plan on going into both France and Spain, you need two different International Driving Permits, not one. Complications, complications, more red tape back again.
A new problem facing Brit expats in Spain is that if they want to travel in other European countries, they will now need private medical insurance for the trip because the agreement only covers you for the country in which you reside, it's no longer pan-European as before this debacle. That poses an interesting problem for me if I manage to sell up here and want to keep my car and drive to Britain in it; will I be able to find an insurance company that will cover me for the trip considering my age and heart record? I may have no option but to sell a very low mileage car and take a big hit on that, also creating the interesting question of whether, if I therefore have to allow my present car insurance to lapse, owning no car, will anyone offer me a policy when I want to buy another set of wheels in Britain? Thank you, Boris and Nigel, I hope your monster bites your heads off one day.
