I can understand why the US needs as payback for their ESTA scheme. However the UK does not have a scheme similar to ESTA post Brexit than applies for EU citizens.
Setting something like this up for the UK seems pointless and petty.
Plus there is the issue of the land border between Northern Ireland (UK) and Ireland (EU).
The UK is simply treated the same as everyone else. Nothing petty there.
I expect there will be an exception for Irish and British citizens who travel between the UK and Ireland because of the Common Travel Area.
So then this was introduced but "not a visa" as a way to check people _before_ they get on a plane.
It's a hack basically.
This is likely only for reciprocity with ESTA.
