FSD works perfectly well in the UK (and presumably the rest of the EU) - within limits.
FSD, however, is massively US centric. Lots of straight roads. FSD will take a long time to cope with the single track roads that make up 30% of the roads round here - 50 miles from London. Will it reverse to a lay-by?
Even the main roads connecting towns are single lane each way and can have 90 degree bends (or more), FSD doesn't even slow down.
I'm loving the FSD journey - that's why I got it. However it is FAR from being able to cope with anything over here that isn't a multi lane highway.
Nothing to do with the EU or UN.
