You might actually be better off in a place like London where you might blend into the crowd and people don't pay much attention to each other. Still unlikely to work but if you're just a random guy that's appeared in a small area of the Highlands you're going to stick out a lot more.

I think you would need a lot of money to get out of the U.K., and Western Europe, right away. Ideally, you're in France before the authorities have even scrambled.

If you did have access to a lot of cash then I think you could probably avoid recapture in places like Africa, Asia, and the Middle East. Somewhere with little cultural overlap. Maybe South America.
