Couple of comments to help clarify some of the above back and forth...
First, yeah, it has been discussed, but a break due to the pandemic, and the rise of contactless has pushe the topic to the back burner.
Second, yes, lots of US cards 'can" get a PIN, but it is only for cash advance at an ATM, not purchases, this is not the same thing, I would estimate that you can get a Cash Advance PIN for dozens of cards out there, a PIN for purchase for maybe a dozen or two, and a PIN priority (meaning it will require a PIN first) for maybe a half dozen cards, if that. If you travel often a PIN, or PIN priority card is worth seeking out, that is what I did, never, ever, have an issue.
Contactless capabilities gaining traction help, but they do have limits. Usually there is a Dollar limit, something like 100 GBP in the UK and maybe 50 to 100 euro in the EU. OK for snack and many purchases, two highspeed train tickets from a machine? you hit that limit quickly, might have to purchase one at a time, or find a manned counter to sign. As someone mentioned, merchants were quick to get simple contactless terminals, change out of ticket machines, parking slips, tolls, and other devices is much slower to adopt due to cost and retrofit capability.
